Efficient photoluminescence of Dy3+ at low concentrations in nanocrystalline ZrO2

Spectroscopic and photoluminescence properties of Dy3+-doped lead tungsten tellurite glasses for laser materials

“…Appropriate combinations of blue (B) and yellow (Y) emissions produce white light in addition to the generation and control of different colors in solid state displaying devices [25][26][27]. The generation of white light by LTTDy glasses has been analyzed in the frame work of the chromaticity color coordinates.…”

Enhanced Luminescent Properties in Tm3+/Dy3+Co-doped Transparent Phosphate Glass Ceramic

“…For the Dy 3+ doped sample, monitoring the Dy 3+ emission at 574 nm, corresponding to the 4 F 9/2 ĺ 6 H 13/2 transition, the excitation maximum is located around 347 nm corresponding to 6 H 15/2 ĺ 6 P 7/2 transition. The other secondary excitation peaks, detected around 321 nm, 363 nm and 385 nm comply with the transitions 6 H 15/2 ĺ 6 P 3/2 , 6 H 15/2 ĺ 6 P 5/2 and 6 H 15/2 ĺ 4 F 7/2 , respectively [18]. Based on the excitation spectra, the 353 nm light is chosen as the pumping source.…”

La0.90Dy0.05Nb2O7 nanosheet phosphor and its multilayer films with enhanced host excitation-mediated photoluminescence

“…The latter one belongs to the hypersensitive transition, which is strongly influenced by the environment [25][26][27]. In the present paper, we report the preparation and PL properties of Dy 3+ -photoactivated La 0.90 Dy 0.05 Nb 2 O 7 perovskite nanosheet and its multilayer films.…”
