Abstract (sommario):

The glasses of the series (1-x)[0.5ZnO-0.1B2O3-0.4P2O5]-xMoO3 with 0 ≤ x ≤ 0.6 were prepared by slow cooling of the melt. These glasses were characterized by the measurements of density, molar volume, chemical durability, glass transition temperature and the thermal expansion coefficient. The density and molar volume of the glasses increase with increasing MoO3 content. All glasses crystallize on heating and their crystallization temperature decreases with increasing MoO3 content. An incorporation of MoO3 into the parent borophosphate glass results in a substantial decrease of their glass transition temperature and also of their chemical durability. The observed changes were ascribed to the gradual replacement of stronger P-O-P bonds by weaker Mo- O-P and Mo-O-Mo bonds. ESR spectra revealed the presence of Mo5+ ions responsible for the blue colour of the glasses and the relative ratio of Mo5+/Mototal decreases with increasing MoO3 content.

Abstract (sommario):

Abstract: Zinc lithium lead calcium borophosphate glasses containing Er3+ in (40- x):P2O5:10ZnO:10Li2O:10PbO:10CaO:20B2O3:xEr2O3 (where x=1, 1.5,2 mol %) have been prepared by melt-quenching method. The amorphous nature of the glasses was confirmed by x-ray diffraction studies. Optical absorption, Excitation, fluorescence and Transmittance spectra were recorded at room temperature for all glass samples. Judd-Ofelt intensity parameters Ωλ (λ=2, 4, 6) are evaluated from the intensities of various absorption bands of optical absorption spectra. Using these intensity parameters various radiative properties like spontaneous emission probability, branching ratio, radiative life time and stimulated emission cross–section of various emission lines have been evaluated. Keywords: ZLLCBP Glasses, Optical Properties, Judd-OfeltTheory, Transmittance Properties.

Abstract (sommario):

A series of glasses with composition of xPbO-(50-x)ZnO-yB2O3-(50-y)P2O5 with 0 x 50 mol% and 10 y 20 mol% were prepared by melt quenching technique, with 30 minutes pre-heating and 10 minutes for melting. The structural properties of prepared samples were studied using Fourier Transform-Infrared spectroscopy. The glasses were mainly based on PO2, BOP and BO3 unit. In order to obtain luminescence properties, another series of sample at composition 20PbO-30ZnO-10B2O3-40P2O5 doped with Fe2+, Ti2+, Y2+ and Nd2+ were prepared. These samples were investigated using Photoluminescence Spectroscopy with different excitation wavelength to compare results. Results showed that with the presence of rare earth and transition metal ions as activator in lead zinc borophosphate glass system give rise to luminescence of visible light.

Abstract (sommario):

Abstract The Nb3⁺ doped Zinc Borophosphate glass (30B2O3 +35P2O5+5TiO2+10ZnO+9LiCO3+10 BaCO3+1NbO2) has been synthesized successfully using melt-quenching method. The powder X-ray diffraction (XRD) analysis was used to find the glass nature of Nb3⁺ doped Zinc Borophosphate glass. The functional group of Nb3⁺ doped Zinc Borophosphate glass was recognized using Fourier-transform infrared spectroscopy (FTIR) analyses. Linear optical properties of the Nb3⁺ doped Zinc Borophosphate glass were studied using UV–vis–NIR spectrum in the room temperature. Mechanical behaviour of Nb3⁺ doped Zinc Borophosphate glass was examined through Vicker’s hardness method. The mechanical properties of Nb3⁺ doped Zinc Borophosphate glass was examined with various loads. The emission transitions of Nb3⁺ doped Zinc Borophosphate glass was studied using Photoluminescence analysis. The CIE diagram of the Photoluminescence was examined. Gamma ray shielding parameters such half value layer, mean free path and mass attenuation coefficient of Nb3⁺ doped Zinc Borophosphate glass were studied using Phy-X software.

Abstract (sommario):

Zinc antimony borophosphate glasses has been determined for [10P2O5 –40B2O3 –xSb2O3 –(50–x)ZnO] and composition of [10P2O5 – 40B2O3 –40Sb2O3 –10ZnO] has been doped with 1 mol% of rare earth (Eu, Nd, Sm, Er). The functions of compositional changes on their structural features were examined using X–Ray Diffraction (XRD) to detect the amorphousity phase present. While Fourier Transform Infrared (IR) Spectroscopy were used to identify the presences of vibrational modes and band assignments of phosphate, borate, antimony, zinc and Rare earth ion in the system. XRD results expose that crystalline phase changes with different amount of zinc and antimony substitution. Hydroxyl group absorption also vary due to this composition changes and clearly shown in IR spectroscopy in the ranges 1400–4000 cm–1. Result of IR spectroscopy indicated that bands around 1440 cm–1 and 760 cm–1 was ascribed to the vas(B–O–B) and vs(P–O–P) vibration respectively. The changes of this vibration indicated that P–O–B linkage was formed near 660 cm–1. The modification of zinc antimony borophosphate glasses with rare earth was studied and showed present of rare earth ion in the glass system does not change the structural features.
