摘要 本文通过优化晶体生长工艺,采用提拉法生长了浓度分别为0.5at%、1at%和3at%系列高质量Pr3+掺杂Lu3Al5O12晶体。通过ICP、透射光谱、荧光光谱等系统研究了晶体性能。结果表明:Pr∶LuAG晶体在紫外光范围内有较强吸收峰;X射线激发荧光峰较光致激发荧光峰发生蓝移;随掺杂浓度的提高,晶体中Pr3+的浓度成比例提高,同时晶体的透过率及荧光光谱强度都有相应提高。 Abstract：P r-doped Lu3Al5O12 （Pr： LuAG） single crystals were grown by Czochralski （Cz） method with praseodymium concentration 0. 5at%, lat% and 3at%, and high quality crystals optimizing the measured. The growth parameters. The ICP, transmission spectra, fluorescence were obtained by spectra etc were results show that Pr： LuAG crystals have strong absorption peaks in the UV range; X-ray excited fluorescence peak brings a blue shift compared with light-excited fluorescence peaks; the concentration of Pr^3＋ in LuAG increased as the original doping concentration increasing, and the transmittance and fluorescence intensity also increased at the same time.
