摘要：

Fluorescein-silica nanoparticles as hybrid dyes were prepared by a reverse microemulsion method. The nanoparticles exhibited suitable optical properties to be combined with a 450 nm LED to achieve white-light emitting diodes. Their optical and thermal stability were investigated. Upon excitation at 450 nm the composite film comprised of fluorescein-silica nanoparticles and silicone led to white light with CCT around 6600 K and a maximum luminous efficacy of 26 lm W-1.
