Solid-state lighting (SSL) is considered a fourth-generation illumination source of lighting, which saves energy and reduces environmental pollution, substitutes for current conventional incandescent and fluorescent lamps. In this direction, an investigation for efficient, durable and single-phase host matrix through chemical approaches has received greater attention, since they can offer higher luminous efficiencies, excellent colour rendering indices and lower manufacturing costs. The most popular approach for producing commercial WLEDs is a fabrication of InGaN blue LED with a yellow...
