Novel low-temperature synthesis of Y O :Eu nanophosphor using combustion with thioglycerol as fuel for near-UV light-emitting diodes.

Luminescent materials used in flat panel displays, compact fluorescent lamps, and light-emitting diodes require high purity, uniform particle size, clean surfaces, spherical shape, and dense morphology to ensure long-term stability. Y O :Eu is a widely studied red phosphor known for its characteristic photoluminescence (PL) emission at 613 nm with near-UV excitation at 392 nm. Many methods have been explored to synthesize Y O :Eu nanoparticles with exceptional purity, consistent phases, and uniform particle sizes.
