Up-conversion luminescence properties of Yb3+–Ho3+ co-doped CaLa2ZnO5
Source abstract
Abstract
Abstract A class of Yb 3+ /Ho 3+ ions co-doped CaLa 2 ZnO 5 (CLZ) up-conversion (UC) phosphors were synthesized by sol–gel method. Under 980 nm excitation, UC spectra consist of two prominent emission bands centered at 545 and 662 nm originating from 5 F 4 , 5 S 2 → 5 I 8 and 5 F 5 → 5 I 8 transitions of Ho 3+ ion, respectively. The UC spectra as a function of the concentration of the dopants were also investigated to determine the optimal composition. The possible UC mechanism was proposed, and lifetime measurements were also carried out to support our proposal.
