Photoluminescence of cerium-doped (Ca1-xSrx)(3)RE2Ge3O12 garnet phosphors for solid state lighting: Relating structure to emission

Abstract:

A novel family of cerium-doped garnet oxide phosphors, (Ca 1-xSrx)3RE2Ge3O 12:Ce,Li (2%, 2%) (x=0-1, RE = Y, Lu), was prepared using a conventional high-temperature ceramic route and was found to exhibit green luminescence under blue excitation. These compounds were characterised by synchrotron X-ray diffraction and photoluminescence spectroscopy. The results from this study were compared with other known Ce-doped garnets, including yttrium aluminium garnet, leading to a deeper understanding ...
