This work deals with the spectroscopic properties of praseodymium doped single crystalline lutetium aluminum garnet (LuAG:Pr3+). A special focus was set on temperature- and time-dependent spectroscopy. Beyond the well-known down-conversion luminescence of LuAG:Pr3+, also UV-A/B up-conversion luminescence under excitation with a 488 nm laser was thoroughly investigated. Furthermore, the results of the spectroscopic investigations on the single crystalline material were supplemented and compared with measurements on a microscale powder sample.

In addition, to the spectroscopic investigations, mechanistic considerations are presented to obtain a closer look at the up-conversion process in LuAG:Pr3+. We promote the thesis of a temperature-dependent energy transfer up-conversion mechanism.

单晶Lu 3 Al 5 O 12:Pr 3+的发光和上转换

这项工作涉及do掺杂的单晶铝石榴石(LuAG:Pr 3+)的光谱性质。特别着重于温度和时间相关光谱。除了众所周知的LuAG:Pr 3+下转换发光外,还对488 nm激光激发下的UV-A / B上转换发光进行了深入研究。此外,对单晶材料的光谱研究结果得到了补充,并与微粉状样品的测量结果进行了比较。

此外,在光谱研究中,还提出了机械方面的考虑,以便更仔细地观察LuAG:Pr 3+中的上转换过程。我们提出了一种与温度有关的能量转移上转换机理的论文。
