Abstract EN
Nano-Ce-doped Y3Al5O12 (YAG:Ce) powders were synthesized by using a sol-gel low temperature combustion method, followed by thermal annealing.
The annealing temperature for enriching nanoparticles was optimized and found to be 1000°C.
The process for enriching uniform nanoparticles of YAG:Ce powder was carried out by using the nanosteam technique (NST).
The nanoparticles obtained from this NST treatment had a size in the range of 9–20 nm.
Measurements of the photoluminescence spectra of the dispersed YAG:Ce nanoparticles solutions showed a blue shift in the photoemission with a value of ca.
10 nm in the green region.
WLEDs made from the blue LED chip coated with the nano-YAG:Ce + MEH-PPV composite epoxy exhibit white light with a broad band luminescent spectrum and a high color rending index (CRI).
The photoluminescence spectra of the YAG:Ce nanoparticles showed a potential application of the prepared nanostructured YAG:Ce phosphor not only in energy-efficient solid-state lighting, but also in optoelectronic devices, including organic composite solar cells.
In addition, it is suggested that NST can be applied for the enrichment of uniform inorganic nanoparticles.
