Efficient up-conversion emission and energy transfer in LaAlO3 doped with Er3+, Ho3+, and Yb3+ ions
Source abstract
Abstract
Abstract The spectroscopic properties of LaAlO 3 polycrystals doped with Er 3+ , Ho 3+ and Yb 3+ ions have been investigated. Very efficient up-conversion emission occurs upon IR excitation. The strongest luminescence has been observed for a sample doped with Er 3+ , Ho 3+ , and Yb 3+ ions simultaneously and annealed at 1500 °C. An efficient energy transfer to Yb 3+ ions is observed when Er 3+ or Ho 3+ ions are excited. The energy transfer mechanisms are proposed.
