Abstract
In this work, we present for the first time the results on crystallization and investigation of the luminescence properties of new prospective phosphors based on single crystalline films (SCFs) of Ce3+-doped Ca2YMgScSi3O12 silicate garnet, grown by the liquid phase epitaxy (LPE) method onto Y3Al5O12 (YAG) substrates. The luminescence properties of Ca2YMgScSi3O12:Ce SCFs were compared with the properties of the reference YAG:Ce SCF sample. The influence of thermal annealing at 1000–1300 °C in a N2/H2 reducing atmosphere on the optical properties of Ca2YMgScSi3O12 SCFs was investigated as well. The results of this research can be suitable for the development of a new generation of white LED converters and scintillators based on the epitaxial structures of Ca2+–Si4+ containing garnets, grown by the LPE method onto undoped or doped substrates of garnet compounds.
