ENHANCING PHOTOMETRIC PERFORMANCE OF YAG:CeCERAMICS: INVESTIGATING THE ROLE OF ANNEALING IN RADIATION-ASSISTED SYNTHESIS

Ceramic samples of cerium-doped yttrium aluminum garnet (YAG:Ce) were successfully synthesized utilizing a high-powered electron flux field with considerable energy level 1.4 MeV and power density 23 kW/cm2. The ceramics formed in remarkable time span just one second from specifically prepared mix yttrium, aluminum, cerium oxides. process radiation-assisted synthesis within radiation fields fundamentally deviates the methodologies commonly employed today. Analyzed diffraction patterns closely align those documented for YAG:Ce crystals, both peak position proportion. Furthermore, every sample consistently demonstrated space group symmetry Ia-3d. luminescence excitation spectra this study resemble produced by other methods -based phosphors. bands exhibit high efficiency, intensity ratios UV vary among studied ceramics' radiation-to-luminescence conversion efficiency was found to be impressive, achieving scores 0.57 0.48 industrial phosphors SDL 4000 YAG-02, respectively. It also observed that an increase quantum could achieved via high-temperature annealing. High underscores potential outlined luminescent method.
