摘要: Many salts of polynuclear carboxylic acids, phenols, amines, and sulfonic acids adsorbed on paper, silica, alumina, other substrates exhibit strong triplet phosphorescence at room temperature, with no evidence quenching by oxygen. No has been observed nonionic materials. The spectra are similar to those frozen solutions -196 degrees C, the technique provides a simple means demonstrating phenomena, identifying unknown materials, investigating states.
