Effect of Annealing Temperature on Growth Particles of YAG: Ce+3 Phosphor and White Light Chromaticity Values
In the present work, white-emitting Y3Ais012:xCe3 (x = 0.04) nanophosphor, in the form of powder, were synthesized by a novel technique that uses continuous wave-C02 laserinduced solution combustion synthesis (LISCS, 40 W) using metal nitrates as precursors and urea as fuel. By covering blue light-e...

| description | In the present work, white-emitting Y3Ais012:xCe3 (x = 0.04) nanophosphor, in the form of powder, were synthesized by a novel technique that uses continuous wave-C02 laserinduced solution combustion synthesis (LISCS, 40 W) using metal nitrates as precursors and urea as fuel. By covering blue light-emitting diodes (blue-LED, 445 nm), white light emission (WLED) was generated. The annealing temperature with fixed time (5 h) for phosphor powder was optimized and found to be 1050 oc. The crystallinity, structure, luminescent properties and chromaticity were characterized by X-ray diffraction (XRD), field emission-scanning electron microscope (FE-SEM), transmission electron microscopy (TEM), photoluminescence emission (PLE), electroluminescence (EL) and standard CIE 1931 chromaticity diagram, respectively. The results show that the obtained YAG:Ce+3 phosphor annealed at 1050 oc has good crystallinity with pure phase, low agglomeration with spherical shaped particles and strong yellow emission, offering cool-white LED with tuneable correlated color temperature (CCT) and a good color rendering index (CRI) compared to those prepared by annealing at 950 oc. 850 oc and as-prepared phosphor powders. |
