文摘

Excitation and emission spectra of Pr³⁺:PLZT ceramics have been studied. Several emission bands were measured under blue laser excitation, which correspond to ³P₀→³H₄, ¹D₂→³H₄, ³P₀→³H₄ and ³P₀→³F₂ transitions of trivalent Pr³⁺. Their integrated emission intensities were determined. The blue-to-red luminescence intensity ratios of Pr³⁺ depend significantly on free sintering/hot pressing methods used for PLZT fabrication and activator concentration. Luminescence decay curves for the ¹D₂ state of Pr³⁺:PLZT ceramics are also presented and discussed.
