Abstract

A method of manufacturing optoelectronic components includes spraying a fluorescent layer of an optoelectronic component onto a substrate, the substance or the substance mixture of the fluorescent layer including an electric charge when sprayed on, and wherein the electrically charged substance or the at least partially electrically charged substance mixture includes a larger electric potential when the fluorescent layer is sprayed on than at least one area of the substrate; and locally adjusting the thickness of the fluorescent layer of the sprayed-on fluorescent substance when spraying on the fluorescent layer onto the substrate by an electric potential gradient.
