| Summary: | Title screen Multilayer Y3Al5O12 (YAG)/MgAl2O4 (MAS) ceramics doped with europium and cerium ions exhibiting functionally graded properties was consolidated by the SPS method using during layer-by-layer formation powders approach. The optimal modes for YAG/MAS ceramics doped with rare earth ions preparation were obtained during the SPS process. It was observed that at the isothermal exposure stage at a temperature of 1450 °C shrinkage process stops. Introduction of CeO2, Eu2O3 into the YAG/MAS ceramics leads to a shift in the range of intense shrinkage to lower temperatures. Morphological, optical and luminescent properties have been studied in detail for fabricated YAG/MAS ceramics with different arrangement of the layers. The luminescent properties using time-resolved cathodoluminescence (CL) and steady state photoluminescence (PL) were investigated in detail. The spectral dynamics in nanosecond and millisecond time range was demonstrated after e-beam excitation. The PL efficiency of YAG/MAS ceramics and nature of luminescence centers were analyzed. The novel kind of YAG/MAS functional ceramics could be promising candidate for efficient luminescent converter Текстовый файл AM_Agreement |
