Room Temperature Phosphorescence

The organic mechanoluminescence (ML) happens at the crack surface under force, and the ML composition is becoming more complicated, extending from the normal fluorescence to phosphorescence, persistent room temperature phosphorescence and the photo-sensitive ML.

A new kind of solid matrix, glasses from sugars, was developed for trace organic analysis. Clear glasses of glucose and trehalose were prepared by evaporating the sugar solutions onto solid supports. It was determined that the ratio of methanol to water was very important in forming a clear glass. Also, glasses made from pure trehalose often cracked. However, with the addition of 8–10% NaCl to the trehalose, no cracks were formed. Clear and rigid glasses of both glucose and trehalose/NaCl were obtained on quartz plates. Strong room-temperature fluorescence (RTF) and room-temperature phosphorescence (RTP) were obtained from benzo[ f]quinoline (B[ f]Q), 4-phenylphenol (4-PP), (tetrol I-1), triphenylene, and phenanthrene. The limits of detection (LODs) of both the RTF and RTP for 4-PP and B[ f]Q in the glasses were in the subnanogram milligram range.

Technical Report

AbstractGuidelines for measuring the luminescence of inorganic compounds, metal complexes, and organometallic compounds are described. Common textbooks and manuals describing luminescence measurements are usually targeted for organic compounds, and are not always suitable for inorganic and organometallic compounds, which emit room-temperature phosphorescence. The report describes problems that researchers may confront while recording emission data and elaborates clear procedures to avoid these problems and provide adequate standardized protocols.
