The composite exhibits complementary blue and yellow emissions, resulting in bright white light production. Electron microscopy indicates ?70 nm particle formation with a surface area of ?112 m2/g. Upon excitation with a 405 nm LED, chromaticity coordinates were measured at (0.35, 0.33). Time-resolved emission spectroscopy revealed radiative decay times of ?4.3 ns for C102 and ?4.8 ns for Rh6G, dependent on concentration. Thermal stability was assessed from 273 K to 325 K. The synthesized materials were also tested as coatings on blue LEDs for white light emission and latent fingerprint detection. Detailed photophysics and analyses are discussed in the article. © 2025 Taylor & Francis Group, LLC.encomposite; Coumarin 102; Luminescence; nanosilica; optical material; Rhodamine 6GArticle
