Yellow-green luminous powder is also called photoluminescent pigment glow in the dark pigment,glow powder . Since there is rare earth-activated alkali earth aluminate-Strontium(Sr) in the components,it is long afterglow time glow pigment.
Based on glow brightness ,Yellow-green luminous powder has mainly three types. The luminous data is as following
