Abstract
Strontium aluminate (SrAl2O4) phosphor nanoparticles with Eu2+, and Dy3+ co-doping exhibit high brightness and long afterglow properties, storing light energy and glowing slowly under different conditions. It has been widely studied that SrAl2O4:Eu2+, Dy3+ (SAO) phosphor nanoparticles with a green visible emission can penetrate deep into the tissue, show low self-fluorescence, cause minimal light damage, and are biocompatible. SAO phosphor nanoparticle synthesis and modification mechanisms are outlined in this review. Biological therapies, in addition to the detection of substances in organisms, are provided by these excellent priorities. Despite the existing research, it has been demonstrated that nanostructures of SAO luminescence particles have great potential to be applied to tissue engineering and drug delivery systems. The current scientific achievements can provide a reference for research in the areas mentioned above, as well as stimulate biomedical disciplines to pay attention to SAO luminescence nanoparticles.
