Effect of Mg2+ substitution on enhanced photoluminescence of red orange long persistent phosphor perovskite Sr1-1.5xZr1-yO3-y:xSm3+,yMg2+

Persistent luminescent nanophosphors for applications in cancer theranostics, biomedical, imaging and security

“…These materials, as already mentioned, show the emission of photons long after the excitation process is stopped due to the trapping of charge carriers. Thus, their property of lasting in emission for extended periods of time has earned them the name "long-lasting phosphor (LLP)" [ 41 ]. Several reviews have been published focused on the phenomenon of PerLum but lacking in some aspects of synthesis techniques, properties, or applications [ 19 , 24 , [42] , [43] , [44] , [45] , [46] , [47] , [48] , [49] , [50] , [51] , [52] ].…”
