Photoluminescence

Developments and applications

Abstract

Photoluminescence is one of the most promising innovations in the field of innovative materials, with applications in design and sustainability. Thanks to recent advances in the production of europium and dysprosium-based pigments, it is now possible to obtain long-lasting light emissions (up to 14-16 hours) without any direct energy consumption. This article analyses the physical principles behind the phenomenon, the techniques for applying it to various materials (glass, ceramics, polymers, and fabrics), and the design implications in the fields of signage, safety, landscaping, and environmental well-being. The research also highlights the contribution of photoluminescence to reducing light pollution and saving energy, positioning it as a sustainable alternative to traditional lighting systems. Experiments conducted in academia and industry have demonstrated the feasibility of innovative products, yielding significant benefits in terms of both CO₂ emission reduction and enhanced sensory perception of nighttime spaces. Finally, the article proposes development prospects for the design of photoluminescent materials, highlighting their potential to redefine the relationship between light, the environment and society.
