摘要：

Recent studies in stabilised ZrO2 single crystals reveal that oxygen vacancies and/or their complexes are involved in the luminescent process [1]. Samples of rare earth doped zirconia fibres were pulled by the laser-heated pedestal growth (LHPG) method and their photoluminescence was observed. We report the systematic study of the photoluminescence measured in several samples: ZrO2:Er3+, ZrO2:Er3+:Pr3+:Y3+, and ZrO2:Pr3+:Y3+ The experiments were carried out by pumping the samples with single and multiple UV lines of a Kr+ ion laser (337.5-356.4 nm). Emission spectrum broadening of Er3+ and Pr3+ has been observed and a reproducible strong change in the luminescence behaviour occurs when the excitation power surpasses a certain value.
