Abstract

See full text

A method for forming a light extraction layer including nanostructures, the method including: providing a substrate, the substrate being at least partially transparent to UV light; forming a non-aqueous precursor solution comprising fluorine and an alkaline earth metal to form alkaline earth metal difluoride particles; applying the precursor solution on at least a first side of the substrate; drying the substrate at a first temperature for a first period of time; and baking the substrate at a second temperature, higher than the first temperature, for a second period of time, thereby forming a light extraction nanostructure layer comprising alkaline earth metal difluoride nanostructures on the substrate. Also, a light extraction structure and to a UV lamp including such an extraction structure.
