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{SchroederFischerJuestel2021, author = {Schr{\"o}der, Franziska and Fischer, Stefan and J{\"u}stel, Thomas}, title = {X-ray and VUV excitation studies on Pr3+ activated Li2CaSiO4}, series = {Journal of Luminescence}, volume = {235}, journal = {Journal of Luminescence}, issn = {0022-2313}, doi = {10.1016/j.jlumin.2021.118046}, pages = {118046}, year = {2021}, language = {en} } @article{FischerJuestel2020, author = {Fischer, Stefan and J{\"u}stel, Thomas}, title = {Effective Sensitization of Eu3+ with Ce3+ by suppression of metal-to-metal charge transfer in composite structured TbF3 fluoride particles}, series = {Journal of Luminescence}, volume = {223}, journal = {Journal of Luminescence}, issn = {0022-2313}, doi = {10.1016/j.jlumin.2020.117232}, pages = {117232}, year = {2020}, language = {en} }
