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.}, language = {en} } @article{LaubeHerdenSeelbachetal.2020, author = {Laube, Michael and Herden, Benjamin and Seelbach, Egon and Braun, Norbert and Berger, Thomas and J{\"u}stel, Thomas}, title = {Novel Radiation Device for Application in the UV-A and UV-B Range}, series = {ECS Journal of Solid State Science and Technology}, volume = {9}, journal = {ECS Journal of Solid State Science and Technology}, doi = {10.1149/2162-8777/aba4f0}, pages = {065012}, year = {2020}, language = {en} } @article{LaubeJuestel2021, author = {Laube, Michael and J{\"u}stel, Thomas}, title = {On the time and temperature dependent photoluminescence of Pr3+ and Gd3+ doped Lu3Al5O12}, series = {Journal of Luminescence}, volume = {236}, journal = {Journal of Luminescence}, issn = {0022-2313}, doi = {10.1016/j.jlumin.2021.118112}, pages = {118112}, year = {2021}, language = {de} }
