文摘

In this paper we report observation of highly efficient Pr³⁺ 4f–4f emission in ZrO₂ (0.5 mol. % Pr³⁺) fine nanocrystals stabilized by Y₂O₃ (7 mol. % ). The nanocrystals were obtained via a hydrothermal microwave-driven process followed by heat treatment at 1200 °C. The samples excited by 266 or 297 nm light exhibit a remarkable sensitizing of Pr³⁺ photoluminescence. The chromaticity analysis indicates the usability of the studied material as a red luminescent phosphor.
