Solid‐Phase Room‐Temperature Phosphorescence

Abstract

Abstract Solid‐phase phosphorescence (SPP) has become an established approach for the trace analysis of organic compounds. More recently, SPP has been successfully applied to the trace analysis for inorganic species. In this mini review, initially a brief overview of SPP is given. Then the important aspects related to adsorption of the phosphors on the solid phase are discussed. In addition, the basic photophysical aspects of phosphorescence are presented. The physicochemical interactions in SPP, such as the rigidity of the solid phase, effects of oxygen and moisture, heavy‐atom salts, and temperature, are considered. Finally, several recent applications of SPP to both organic and inorganic compounds are discussed.
