Abstract

Crystals of CsMgCl₃ doped with Tm³⁺ exhibit a strikingly strong up-conversion luminescence when the ¹G₄(D) state is pumped under pulser excitation at 465 nm. The most intense up-conversion emissions, which appear in the near-UV, originate from the ¹I₆(F) state at 34100 cm^-1. Weaker features from the ¹D₂(E) state at 27700 cm^-1 are also observed. At 11 K the ¹I₆(F) and ¹D₂(E) emissions exhibit the rise and fall kinetics consistent with cross-relaxation from photoexcited pairs
