Controllable crystal form transformation and luminescence properties of up-conversion luminescent material K₃Sc_0.5Lu_0.5F₆: Er³⁺, Yb³⁺ with cryolite structure

Abstract

Controllable crystal form transformation can effectively influence the up-conversion luminous intensity of cryolite materials.

Upconversion luminescence and temperature sensing properties of Ho3+,Yb3+-codoped Bi2WO6

“…According to the literature, 20 the absolute thermometry sensitivity S a and the relative thermometry sensitivity S r can be expressed as follows:…”
