Resumen
In recent years, lanthanide-ion doped nanocrystals have attracted considerable attention for its promising applications in multiplexed biological labeling. These materials can convert near-infrared (NIR) light into visible and offer low autofluorescence, high resistance to photobleaching, high penetration depth and large anti-Stokes shifts. With the development of these techniques, the ability to manipulate multicolor output has become more important for its biological and photovoltaic applications. This review mainly focuses on the recent development of various approaches for the multicolor tuning of lanthanide-ion doped upconversion nanoparticles.

Resumen
AbstractUltrathin two-dimensional (2D) materials have drawn great attention in recent years due to their promising applications in biomedicine and atomically optoelectronic devices. In this work, we have fabricated a 2D In2Se3 nanosheet doped with Nd3+ ions via the two-step method of solid phase synthesis and liquid exfoliation. Owing to the special inner 4f-4f energy level transitions, lanthanide ions can emit photons with almost the same energy in different environments. Here, a stable near-infrared luminescence from Nd3+-doped 2D In2Se3 nanosheets has been realized, which includes emission bands around 910, 1057, and 1324 nm. The doping of Nd3+ ions extends the emission region of In2Se3 nanosheets. Moreover, the photoluminescence mechanism of Nd3+ ions was investigated through a series of optical measurements. This work not only provides a reliable method to fabricate lanthanide ion-doped 2D materials but also possesses a great significance for luminescence study of lanthanide ions in the 2D matrix.

Resumen
Well-defined and mono-dispersed lanthanide-ion-doped NaYF4 up-conversion nanoparticles (UCNPs) were synthesized via thermal decomposition using lanthanide oleate as the precursor. By rational selecting the dopant pairs of the doped lanthanide ions (Y3+, Yb3+, Er3+ and Tm3+) with accurate molar ratios, three-primary-color (RGB) UCNPs which exhibited green (UCNPs-G), blue (UCNPs-B) and red (UCNPs-R) fluorescence, respectively, were prepared. The X-ray diffraction (XRD) patterns showed that the three UCNPs were purely hexagonal-phase NaYF4 crystals. Transmission electron microscopy (TEM) images revealed that the synthesized UCNPs exhibited well-defined nanosphere morphology with uniform size distribution. The average diameters were 23.95±3.35 nm for UCNPs-G, 20.63±2.59 nm for UCNPs-B, and 19.24±2.37 nm for UCNPs-R, respectively. After surface modification employing polyacrylic acid (PAA) as modifier, the obtained UCNPs were converted to be hydrophilic, which can be used as fillers to construct luminescent polymer films and luminescent ink in anti-counterfeiting application.

Resumen
Cette thèse montre l'intérêt de l'amplification optique et des lasers à fibres dopées par des ions de terres-rares pour l'instrumentation et les capteurs à fibres optiques. Nous détaillons les avantages et les inconvénients d'une telle technologie placée dans son contexte d'optique intégrée, ainsi que ses perspectives d'utilisation. Apres rappel de la théorie de la propagation guidée dans les fibres optiques, les technologies permettant de réaliser des fibres optiques dopées sont décrites. Une étude comparative des méthodes d'analyses de préformes et de fibres dopées permettant de déterminer leurs profils de guidage et de dopage est également présentée. Le comportement amplificateur des fibres optiques dopées est ensuite décrit théoriquement en insistant sur les limites fixées par l'élargissement inhomogène de la transition laser. L'évolution du gain intégré de la fibre est mise en évidence en fonction des paramètres influants (longueur, rayon de dopage. . . ) en soulignant l'intérêt d'un rayon de dopage optimisé. Le seuil d'accrochage du laser est modélisé par des équations et des abaques sans dimension déterminant la longueur de fibre optimale en fonction des pertes de la cavité laser. La conception générale du laser à fibre est ensuite synthétisée et les technologies des composants d'optique intégrée adaptés à la fibre amplificatrice le constituant sont comparées. Les techniques expérimentales concernent principalement l'étude de l'accordabilité par excitation sélective de sites et de la limitation du gain par émission stimulée sur la transition de pompage induisant une absorption résiduelle non saturable ; l'étude des effets de transferts dans les fibres dopées par luminescence coopérative : l'étude d'un procédé de changement de valence par irradiation y conduisant à une réduction des ions uranium placés en matrice verre fluoré (zblan) ; la démonstration d'un effet laser à trois niveaux, fonctionnant en régime continu et en contre-réaction externe par réseau
