Ratiometric optical thermometry is one of the most promising techniques for contactless
temperature sensing. However, despite the efforts devoted in the last decades, the …

The development of nanomaterials with high sensitivity to external stimuli such as
temperature is critical to investigate the driving force of not only biological processes but …

Bismuth-based fluoride nanocrystalline particles have recently attracted much attention as
hosts for luminescent ions such as lanthanides (Ln) being proposed for lighting devices and …

Co-doping of rare-earth-doped glasses with silver is a promising option to enhance the
photoluminescence of rare-earth (RE) ions. The enhancement of the emission of erbium has …

In this work, a novel Ag nanoparticle doped bismuth glass frit was fabricated by the melt-
quenching method. The effect of varying heat treatment temperature on the structural and …

The role of the material structure in the energy transfer between Ag and Tb 3+/Yb 3+ ions is
studied in silica-soda-zirconia sol-gel glasses and glass-ceramics. The preparation of Tb 3+ …

Various nonlinear optical (NLO) phenomena observed in liquid suspensions of metal
nanoparticles (NPs) and metal nanoclusters (NCs) have received considerable attention in …

Silver quantum clusters ([Ag m] n+ QCs) are a type of efficient broadband fluorescence
centers with m and n related quantum size effects but usually lack chemical and thermal …

In this work, the impact of Ag 2 O on the thermal, structural, and Near-IR luminescence of Er
3+ doped calcium-fluorophosphate glasses is investigated. The amount of silver oxide in the …

This chapter discusses transparent glass ceramics activated by rare earth ions as frequency
converters based on energy transfer. These materials, in either bulk or thin-film form, may be …
