Photoluminescent Printed Fabrics: An Innovative Solution to Natural Nightlight

Conference paper

Abstract

Photoluminescent pigments are rare earth-based luminous materials activated by divalent europium. A photoluminescent pigment emits a bright phosphorous shade on excitation by daylight, incandescent, fluorescent, or ultraviolet light. It exhibits a high initial brightness and a long afterglow. Limited literature is available to guide textile and fashion designers on how these pigments can be used to create novel illuminated surface patterns. Patterns may be created of different intensity of luminescence for different application and products ranging from safety to fashion. Therefore, this research aims to systematically study the properties and design potential of photoluminescent blue pigments on textiles, printed by screen-printing method. The objective of this research is to study the effect of the concentration of photoluminescent pigments of different particle size on the emission of photoluminescence (luminosity and decay). The results are also correlated with the visual perception of photoluminescence by users in a nighttime environment.
