Description
Summary:Transparent and homogenous T2.9Al5O12:0.1Ce3+(TAG:Ce3+) phosphor film with thickness of 5µm and nano-crystalline particles about 60nm was firstly synthesized by sol-gel technology via 40 layers deposition, which introduced the nitrates combustion process into the conventional sol-gel method using terbium, cerium, aluminum nitrates as precursors, glycine and urea as fuel. The as-synthesized TAG:Ce3+phosphor film exhibited good optical properties with strong absorption in the ultraviolet-light and blue-light range, and considerable photoluminescence performances, which displayed a broad emission peak centered at 551nm with a quantum yield (QY) of 49% under 457nm excitation and an enlarged full width of about 10nm at the half maximum as well as a red-shifted emission of about 19nm, in contrast to the commercial YAG:Ce3+phosphor tested, which would be suitable for application in solid-state devices such as WLEDs and display systems. •TAG:Ce3+film packed with nano-particles was firstly prepared by sol-gel method.•TAG:Ce3+film with 5µm thickness was achieved via 40 layers depositions.•It exhibited good transparency in the visible light range.•It displayed strong absorption in the ultraviolet-light and blue-light range.•It showed broad emission peak at 551nm with a QY of 49% at 457nm excitation.
