Tunable luminescence thermal stability in YV_xAs_1−xO₄:Eu³⁺ through the introduction of As⁵⁺ ions for remote temperature sensing applications

Abstract

Thermal nonradiative depopulation processes of excited levels significantly influence the potential application of phosphors. The high efficiency of thermal quenching of luminescence can limit a phosphor’s potential applications as well...

Clarifying concentration quenching mechanisms by lattice site-occupation and luminescence kinetics of Eu3+-activated Cs2Mg2Mo3O12

“…[7][8][9][10] Among them, the luminescence spectrum of Eu 3+ ion is characterized by sharp lines from 5 D 0 -7 F 0,1,2,3,4,5,6 transitions, 11,12 which is the best choice for red-luminescent components. [13][14][15][16][17][18] However, as an activator, the major weakness of Eu 3+ is low oscillation strength in the visible wavelength region (o10 À6 ) 19 because of the f-f forbidden transitions. Consequently, an appropriate host is important for Eu 3+ to achieve efficient red-luminescence via the energy transfer (CT) process.…”
