摘要:
Room-temperature phosphorescence (RTP) emission was detected from several organic substrates using a solid surface composed solely of alkali salts. This technique yields detection limits comparable to the popular polymer-salt and filter paper methods. More importantly, the alkali halide matrix environment requires no special drying processes, has a simple, reproducible sample preparation procedure, and yields no interfering background RTP.
