Transparent luminescent Y 2.9 Ce 0.1 Al 5 O 12 (YAG:Ce 3+ ) phosphor films (PFs) with thickness of 4.30 μm 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:Ce 3+ 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.
