Abstract :
Two new systems, namely LaLuO3 and Lu4Al2O9 doped with cerium ions, have been investigated. The materials have been elaborated in the form of polycrystalline powders by melting the component oxides and by solid state reaction techniques and in the form of single crystal fibers grown by the laser heated pedestal growth (LHPG) method. The optical spectroscopy was carried out in the UV and VUV regions using laser and synchroton radiation and their fluorescence and scintillation mechanisms were analyzed.
