High Eu³⁺ concentration quenching in Y₃TaO₇ solid solution for orange-reddish emission in photonics.

ABSTRACT: We report the synthesis of a Y₃TaO₇ solid solution containing a high Eu³⁺ concentration (from 7 up to 50 mol%) and investigate how Eu³⁺ influences the Y₃TaO₇ crystallization process. To this end, we evaluate the Y₃TaO₇ structural features and photoluminescence properties after Eu³⁺ introduction into the Y₃TaO₇ lattice. The higher the Eu³⁺ ion concentration, the more stable the crystallization process of the Y₃TaO₇ phase seems to be. The Eu³⁺-containing Y₃TaO₇ displays intense orange-reddish, broad band emission because Eu³⁺ occupies different symmetry sites in the host and causes inhomogeneous b
