Preparation and Reliability of Wearable Blue Light-Storing Buttons

Abstract

The potential applications of light-storing materials have stimulated the exploration of the preparation of wearable light-storing buttons. In this study, Sr2MgSi2O7:Eu2+, Dy3+ was mixed with unsaturated polyester resin in proportion as a light-storing material. A blue phosphorescent button with high stability and long afterglow time is obtained through the dispensing method. The surface, cross morphology, phase structure, photoluminescence spectrum, luminescence image, afterglow performance and mechanical hardness of the phosphorescent button were characterized. The results show that the luminescence performance of the phosphorescent button is significantly better than that of the original material Sr2MgSi2O7:Eu2+, Dy3+ after high temperature and high humidity aging, xenon lamp aging, and thermal cycle aging tests. In this study, the afterglow time button of the light-storing button is very beneficial. At the same time, it has also expanded the application of long afterglow materials in the field of smart wear.
