A low-energy milling approach to reduce particle size maintains the luminescence of strontium aluminates

Decreasing the particle size, improving the distribution of the particle size, avoiding a high agglomeration state and maintaining the photoluminescence response of SrAl2O4 doped with Eu2+ and Dy3+ powders is still a challenge in the processing of this phosphorescent material. Here, we explore diffe...
