中文摘要	A comparative study of the photoluminescence properties of three kinds of tetra-ring aromatic hydrocarbon (1-sodium pyrenesulphonate, benz[ alpha ]anthracene and chrysene) solution in the absence of any protecting medium is described It was found that a room temperature phosphorescence signal with different intensities can be induced for these solutions, using only TlNO/sub 3/ or KI as a heavy atom perturber (HAP) and Na/sub 2/SO/sub 3/ as a deoxygenator. An appropriate amount of organic solvent added to the systems of pyrene, benz[ alpha ]anthracene and chrysene is necessary for increasing the solubility and phosphorescence intensity, and the preferable solvent is acetonitrile. For the pyrene, pyrenesulphonate and chrysene systems, a delayed excimer fluorescence accompanied with the room temperature phosphorescence (RTF) emission can be observed, but that for benz[ alpha ]anthracene cannot. The ratio of delayed excimer fluorescence and phosphorescence signals for pyrene, pyrenesulphonate and chrysene systems can be controlled by adjusting the concentration of luminophor, kinds and amount of both organic solvents and HAP. Under the optimal conditions, the RTP signals are proportional to the concentration of the four aromatic hydrocarbons, which means that the RTP properties of the four tetra-ring aromatic hydrocarbons can be used for quantitative analysis.
