- Abstract
This paper covers a new long phosphorescent material which absorbs daylight or lamp light and saves the light during the day and will illuminate after exposure,This nonradioactive, non_poisonous illuminant material will receive ultra_violet and visible lights and its luminous intensity is 10 times more than that of previous phosphorescent materials,meanwhile with more than 24 hrs phosphorescent time and 10 years lifetime,this luminous material may be used for the illuminating purposes such as indicator light.
