Transparent luminescent Y2.9Ce0.1Al5O12 (YAG:Ce3+) phosphor films (PFs) with thickness of 4.30 lm and homogeneous grain size about 80 nm were successfully synthesized by a facile sol-gel method via 40 layers deposition process on quartz substrate. The crystallization, morphology, and optical properties of the as-prepared samples were investigated by X-ray diffraction, scanning electron microscopy, ultraviolet-visible spectrophotometer, spectroffluorophotometry, and absolute photoluminescence quantum yield (QY) measurement system. The as-synthesized YAG:Ce3+ PFs exhibited high transparency, broad absorb peaks at blue-light range and excellent photoluminescence performance with a QY of 47% at 457 nm excitation, which could be used in solid-state lighting and display system applications.
