Long acting noctilucent powder (phosphor)   

Ji'nan Huaiyin Xinxing luminescent materials factory developed new type magnesium strontium aluminate long persistence luminescent phosphor powder development (phosphor), the chemical structural formula is SrMgAl4O8:Eu2+Dy3+, the material and the current market long afterglow materials with different, brightness and afterglow time is higher, the product is the use of abundant rare earth resources in our country development with the domestic and foreign advanced level of high-tech products, it in the daytime or light irradiation the absorption of light energy 10~30 minutes later, a bright fluorescence at night or in the dark a long time, because the product does not contain any radioactive elements and toxic heavy metals, therefore non-toxic, harmless, safe to human body, is a new generation...
