Abstract
Nanophosphor GaZnON was synthesized by combustion using a unimolar mixture of metal oxides and urea as a flux/combustible agent at varying temperature and time; the resulting products crystallized in a single monoclinic phase and had broad PLE spectra (300-550 nm at λex = 350 nm) with the characteristic blue emission that can be utilised in white light-emitting diodes by adding them with red and green light-emitting phosphors and by using a UV LED (λex = 300 nm). Phosphors were examined according to respective package parameters. The blue light-emitting phosphor GaZnON was found to have excellent potential in white light-emitting diode devices by assimilating them with already viable red and green light-emitting phosphors and by stimulating them using a near-UV LED chip with wavelength λex = 300 nm. The possible electron transition mechanism responsible for the luminescence process is also discussed based on the experimental data.
