The blue-green luminous luminous powder is a luminescent material of a poly aluminate structure. This series of luminous powder can continuously emit light for 10-12 hours after absorbing ultraviolet light or visible light for 5-10 minutes, and has the characteristics of high afterglow brightness, long afterglow time and high temperature resistance. Its luminescence time is dozens of times more than traditional zinc sulphate type luminous powder, and it is non-toxic, non-radioactive, environmentally friendly and energy-saving.
(1) The particle size unit is μm and is characterized by a central particle diameter D50.
(2) The brightness unit is mcd/m2, the detection is performed according to the DIN67510 standard, and the D65 standard light source illumination 1000 LX is used to excite for 5 min, and the afterglow brightness of 10 min is detected.
