Spectral Properties of Pr³⁺:La₂O₃ Ceramics

Abstract:

Pr³⁺: La₂O₃ceramics was fabricated by conventional ceramics processing and sintered without pressure in H₂ atmosphere. The structure and spectroscopic properties of the samples were investigated. The strongest excitation peak is detected at 291 nm, which is corresponding to the 4f−5d absorption band of Pr³⁺ ion. Pr³⁺emits green light in La₂O₃ ceramics, the major emission peak located at 512 nm belongs to ³P₀→³H4 transition. Pr³⁺:La₂O₃ owns hexagonal structure and is unstable in air condition, it is easy to absorb water vapor to form La(OH)₃.
