Enhancement of Pr3+ luminescence in TeO2–ZnO–Nb2O5–MoO3 glasses containing silver nanoparticles

The influence of Pr3+ content on luminescence and optical behavior of TeO2–WO3–PbO–Lu2O3 glass

“…Values of all the J-O parameters obtained in this and in our previous work [9] are comparable with those calculated for various Pr 3+ -doped tellurite glasses that, however, exhibit a large scatter covering the ranges 0.6-3.8, 0.9-7.3 and 0.6-6.1 (in units 10 À20 cm 2 ) for X 2 , X 4 and X 6 , respectively [23][24][25][26][27]. Apart from possible calculation errors, this large scatter concerning Pr 3+ -doped glasses may follow from the fact that the standard J-O analysis is particularly sensitive to very small variations in the experimentally determined oscillator strengths.…”

Fluorescence enhancement of Ln3+ doped nanoparticles

“…According to Ref. [16], enhancement by Ag nanoparticles of luminescence of Pr 3 + doped TeO 2 -ZnO-Nb 2 O 5 -MoO 3 glass is due to the influence of large local field on Pr 3 + ions close to Ag nanoparticles. Ref.…”

Microstructural study of Ag2S doped silver molybdate glass-nanocomposites

“…Although structural studies on different tellurite and phosphate glasses have been recently reported [16,17], the investigation of molybdate glass systems has not gained much attention [18]. A few studies on the silver ion conducting molybdate glasses [19] and glass-nanocomposites with dispersed nanocrystalline phases have been reported [20]. It has been observed that the formation of these nanocrsytallites gives rise to different characteristics [20] from those of the host glass matrix, such as the electrical conductivity, which decreases with the increase of the size of the nanoparticles [20].…”
