Afterglow excited by visible light

Most  materials show afterglow property only when illuminated by UV light and not by visible light. This limits further applications since UV light is unsafe. Furthermore, the afterglow from most materials do not perform well at temperatures above 30 degrees Celsius. Our LehMo-Glow samples overcomes the above mentioned drawbacks since the afterglow is excitable by visible light (including white light) and the afterglow is observable by naked eye even at higher temperatures upto  40 degree Celsius. Please see the images below.
