Synthesis And Characterization Of Lanthanum Oxide-Polyvinyl Alcohol Phosphor Nanofibers For White Light-Emitting Diode (Wled)

This study involves the novel application of La2O3-PVA as phosphor nanofibers for white light-emitting diode (WLED). The synthesized of La2O3-PVA phosphor nanofibers by electrospinning process were then applied as phosphor to produce white light. The chromaticity coordinates (CIE), correlated color...
