Abstract

In this paper, we present results authors published initially on the white light emission with broad band (330-465 nm) excitation of the specially prepared nano-phosphor: Eu³⁺: ZnS which is capped with sodium methyl carboxylate and on pure red-light emission from the nano-phosphor when capped with alpha methyl acrylic acid and prepared in a different method. Then we discuss possible methods of future improvement of the white light emission from the nano-phosphor. We then present the cost effective and energy efficient method of obtaining highest quality natural white light sources using such nano-phosphor and blue or near UV blue light emitting diodes. The latter discussion includes the driving circuit for the white LED and powering the LED by concentrated solar photovoltaics for both lighting and waste heat energy storage for completely clean energy natural white lighting sources.
