摘要：

A simple eco-friendly method was employed to generate white light using pomegranate-PVA - curcumin mediated silver nanoparticles (CAg NP-PVA) mixture. The white light emission is obtained by integrating the green emitting curcumin and blue emitting pomegranate extract. Controlling the emission of curcumin with Ag NP-PVA and mixing with pomegranate extract resulted in efficient white light with the Commission Internationale d'Eclairage (CIE) chromaticity coordinate (0.28,0.31). Ag NP-PVA and anthocyanin played a significant role in obtaining CIE coordinate close to that of pure white light (0.33,0.33). The optimized white light emission obtained from pomegranate- CAg NP-PVA mixture is cheap and fairly green in nature.
