Applications of phosphorescence:

The applications of phosphorescence are somewhat limited because of the lack of appropriate instrumentation and the requirement of making measurements at cryogenic temperatures. Therefore, along with the introduction of new instrumental methods and the advances made in room temperature phosphorescence, phosphorimetry is making inroads in the domain of clinical chemistry and within the areas of forensic, environmental and pharmaceutical sciences. In room temperature phosphorescence, phosphorescence spectra obtained from the analyte adsorbed onto solid supports such as filter paper, silica and other chromatographic supports. Various analytes are able to provide room-temperature phosphorescence (RTP) in organised media like as micelles and cyclodextrin solutions. The presence of heavy atoms such as, iodine, silver, leads, etc. in the sample or in the solid matrix is found to improve the sensitivity of the methods and helps within the analysis of complex mixtures through RTP.
