Abstract:

Material properties in the process of tribo-emission decides the characteristics of both spectra and intensity of triboluminescence. ZnS:Mn semiconductor material was proved to be a high emission triboluminescent material in many investigations; Ce- and Yb-doped hexacelsian possess the excellent shortwave triboluminescence character due to f-d electronic transition of doping element with position valances ions; the fracto-mecha-luminescence and photoluminescence spectra of phthalic acid, 4-hydroxy coumarin monohydrate, etc. present obviously a broad ultraviolet and violet waveband emissions, showing the disadvantage of these organic crystals as shortwave triboluminescence materials. Triboluminescence test apparatus of drop tower type have the tribo-emission of impact friction effect; the pin-on-disk type apparatus can perform the triboluminescent experiments with sliding friction mechanism; the twin ring tribometer is used to measure the triboluminescence of polymer material friction rings. These units supply a suitable conditions for obtaining triboluminescence with shortwave emission and persistent high intensity.

Abstract:

Triboluminescence (TL) is a phenomenon of light emission resulting from the mechanical force applied to a substance. Although TL has been observed for many ages, the radiation mechanism is still under investigation. One of the exemplary compounds which possesses triboluminescent properties are copper(I) thiocyanate bipyridine triphenylphosphine complex [Cu(NCS)(py)2(PPh3)], europium tetrakis dibenzoylmethide triethylammonium EuD4TEA, tris(bipyridine)ruthenium(II) chloride [Ru(bpy)3]Cl2, and bis(triphenylphosphine oxide)manganese(II) bromide Mn(Ph3PO)2Br2. Due to the effortless synthesis route and distinct photo- and triboluminescent properties, these compounds may be useful model substances for the research on the triboluminescence mechanism. The advance of TL studies may lead to the development of a new group of sensors based on force-responsive (mechanical stimuli) materials. This review constitutes a comprehensive theoretical study containing available information about the coordination of metal complex synthesis methodologies with their physical, chemical, and spectroscopic properties.

Abstract:

Defects in fiber-reinforced composite structures tend to initiate unpredictably and unalarmed due to local stress concentrations within a composite structure; this has given rise to active monitoring techniques that can quantify the mechanical stress within composites in order to evaluate the structural health. In this paper, triboluminescent mechanisms are used for damage monitoring of composite matrix under flexural loading. Vinyl ester resin is doped with ZnS:Mn phosphors and reinforced with glass fiber whiskers, were subjected to flexural loading while observing both the triboluminescent and acoustic response using a photo multiplier tube (PMT) and micro-mic respectively. Validity of triboluminescent emissions for determining structural integrity of glass fiber / vinyl ester resin composites through individual waveform analysis was examined. Understanding the failure modes through the captured waveform and observed triboluminescent emissions shows that the matrix cracking failure mode tends to lie in the natural frequency range of 2691–2813 Hz. High correlation between the triboluminescent and acoustic signals at matrix cracking at a frequency of 2800 Hz were found. Future research will discuss the triboluminescent and acoustic emissions behavior for delamination and fiber breakage failure modes.

Abstract:

Real-time load monitoring of critical civil and mechanical structures especially dynamic structures such as wind turbine blades is imperative for longer service life. This article proposed a novel sensor system based on the proprietary in situ triboluminescent optical fiber (ITOF) sensor for dynamic load monitoring. The new ITOF sensor patch consists of an ITOF sensor network with micro-exciters integrated within a polymer matrix. The sensor patch was subjected to repeated flexural loading and produced triboluminescent emissions due to the friction between micro-exciters and ITOF sensors corresponding to each loading cycle. The friction-induced triboluminescent intensity directly depends on the loading rate, the coefficient of friction, and the applied load on patch. In general, the triboluminescent intensity increases exponentially with an increase in load. Additionally, the sensor patches comprising the coarser micro-exciters exhibited better results. Similarly, better results were achieved at higher loading rates although a threshold loading rate is required to excite the triboluminescent crystals for this sample configuration. The proposed new sensor has the ability to monitor dynamic continuous applied loads.

Abstract:

AbstractThe photoluminescence of lanthanide complexes originating from f–f transitions is generally sensitized through energy transfer from the ligand to the lanthanide ion in the excited state under UV irradiation. This phenomenon is known as the photo-antenna effect. Luminescence driven by mechanical stimuli, such as tapping or rubbing, is called mechanoluminescence or triboluminescence (TL). In recent years, reports on TL in rare-earth complexes, which have attracted attention as novel luminescent materials that do not require an electrical excitation source, have steadily increased. In this chapter, we focus on triboluminescent lanthanide complexes. Specifically, we introduce the history and detection methods of TL and cite recent examples of materials demonstrating this phenomenon, particularly coordination polymer-like and discrete molecular crystalline lanthanide complexes. Finally, we summarize the application prospects of these complexes as soft crystals.

Abstract:

A novel preparation method of solid state photovoltaic carbon nanotubes (CNT) yarns has been successfully developed by depositing and grafting TiO2 thin films on CNT yarn substrates using a simple sol–gel method and designed for use in structural health monitoring (SHM) applications. The interaligned, ultrastrong and flexible CNYs display excellent electrical conductivity, mechanical integrity and their catalytic properties have been successfully used as working and counter electrodes. The TiO2 nanoparticles have been found to form a homogeneous thin film on the yarn surface, which shows efficient photovoltaic properties with remarkable stability when exposed to simulated solar light (AM 1.5). The yarns’ structure is not altered upon sol-gel treatment and light exposure. The TiO2 film is firmly anchored and the photovoltaic performance is retained even after multiple irradiation cycles. This preparation technique can also be applied to CNT yarn reinforced composite for an innovative in-situ and real-time self damage-sensing properties with infused triboluminescent (TL) materials.

Abstract:

Rotorcraft gas turbine engines are subject to sand particle ingestion problems during take-off, landing, and hovering operations in sandy desert regions. Although most of the rotorcraft gas turbine engines are fitted with inertial particle separators, they are not efficient in filtering out fine sand particles of size of 75 microns or below. Inlet barrier filters may be efficient in filtering fine particles in the intake air-flow, but they cause engine power loss penalty due to significantly high inlet pressure losses. The sand particles in the air-flow cause severe erosion damage on compressor blades, and molten sand glazing coupled with Calcia-Magnesia-Alumino-Silicates (CMAS) attack on hot-section turbine blades. Due to particle impacts and CMAS attack, the coatings on the blades wear out, form cracks and delaminate over time causing huge maintenance burden for rotorcraft gas turbine engines operating in sandy regions. The objective of this research is to discover a revolutionary, in-situ sensing material system that is capable of monitoring the health of propulsion component materials using co-doped luminescent materials in the erosion resistant coatings or thermal barrier coatings (TBCs) of engine components. This paper presents the research efforts and results from the CCDC - Army Research Laboratory, Vehicle Technology Directorate Director's seedling initiative project that investigated the effectiveness of triboluminescent materials interspersed with blade coatings in a layered form for detecting cracks/fractures that may occur in blade coatings due to sand particle exposure under engine relevant conditions. Use of appropriate instrumentations for in-situ luminescence detection methods to identify cracks/fractures in coatings is also discussed.
