TUNING OF LUMINESCENT CONVERTERS BASED ON COUMARINS AND THEIR PHOTOSTABILITY
Abstract
The possibility of using phosphors of the coumarin series in luminescent converters for correcting spectra of LED light sources is investigated. Fine tuning of the emission spectra of phosphors in polymer matrices has been obtained by introducing nonionic surfactants into the matrix. A method for estimating the photostability of luminescent filters is proposed and the photostability parameters are determined.
