A thermodynamically stable and transparent microemulsion system was obtained by dissolving suitable water-to-oil ratio. YAG: Eu 3+ with a single phase was obtained after calcination at 1100 o C for 4 h in air. The formation of single-phase YAG via the microemulsion process is approximately 600℃lower than that via the solid-state reaction. As increasing in the calcination temperature, the phosphors still maintained in the nano-sized range with spherical and dispersed morphology. The emission spectra under the excitation of VUV light confirm the application of YAG: Eu 3+ phosphors for plasma display panels.application/pdf202011 bytesapplication/pdfzh-TW國立臺灣大學化學工程學系暨研究所微乳膠法釔鋁柘榴石奈米粉體螢光材料reporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/9391/1/922214E002036.pdf
