Abstract

Abstract: The physicochemical aspects of functioning the luminescent converters for a rational modification of the emission spectra of light‐emitting diodes are considered. These converters use laser dyes' coumarins 314, 334, and 343 to transfigure the primary light‐emitting diode spectrum. The fine control of the emission spectra of the mentioned coumarins in polymeric matrices was achieved by introducing nonionic detergents. The relevant characteristics of the photochemical persistence of coumarins in the polymer layers are acquired. Abstract : The use of the coumarins‐based luminescent spectral converters allows to transform the emission spectrum of the primary light‐emitting diode source into a spectrum, which mimics that of the natural daylight. The fine control of the emission spectra of the coumarins in polymeric matrices of the spectral converters is achieved by introducing therein the nonionic detergents.
