Effect of host on the radiative (upconversion emission) as well as non-radiative relaxation (laser induced optical heating) in Tm3+/Yb3+ co-doped phosphors

Dwivedi, A.; Kumar, D.; Rai, S.B.; Rai, A.K. (Elsevier B.V., 2020-10)

Tm3+/Yb3+ co-doped YVO4 (YVO:Tm, Yb); GdVO4 (GVO:Tm, Yb); Y2O3 (YO:Tm, Yb); Gd2O3 (GdO:Tm, Yb) and CaAl2O4 (CAO:Tm, Yb) phosphor samples have been synthesized using high temperature Solid State Reaction method. X-ray ...
Enhanced multimodal behaviour of Tm3+/Yb3+ co-doped YTaO4 ceramic material through Bi3+ activation and sensitization: Application as a spectral converter

Roy, A.; Dwivedi, A.; Kumar, D.; Mishra, H.; Rai, S.B. (Elsevier Ltd, 2020-11)

The multimodal [Upconversion (UC), Downshifting (DS) and Quantum cutting (QC)] behaviour of Tm3+/Yb3+ co-doped YTaO4 ceramic material is investigated extensively. The samples are prepared by solid-state reaction method at ...
