Harnessing Perylene Emitters in Soft Hydrogels for\nWhite Light Generation

With\nthe growing demand for energy-efficient lighting solutions,\nthe integration of organic luminophores into light-emitting diode\n(LED) technology offers a promising way of overcoming the limitations\nof traditional inorganic phosphors. This study investigates the potential\nof combining the advantages of organic luminophores (high quantum\nyield, tunability, and low cost) with hydrogel matrices for white\nlight generation. Specifically, the incorporation of two perylene\nderivatives, R-PERY and G-PERY, into a hydrogel composite enables\nthe generation of white light when excited by an inorganic blue LED.\nThe performed analysis reveals that our hydrogel-based converters\nshow remarkable features in emission color modulation and the color\nrendering index. Combined with their softness, water processability,\nand biocompatibility features, this makes them ideal candidates for\nlight-emitting components in sensing devices interfacing with biological\nenvironments.
