Abstract: The effect of temperature and concentration on the fluorescence properties of polystyrene（PS） was analyzed with fluorescence spectrum. The results showed that there were two fluorescence emission wavelength：334 nm and 345 nm in tetrahydrofuran solution，and the fluorescence intensity of PS enhanced as the temperature rises due to cage effect of solvent. In addition，with the increase of the concentration of PS in the solution，the fluorescent intensity decreases nonlinearly，this is because PS dimers are formed in the solvent.

Key words: polystyrene（PS）, fluorescence spectroscopy, dimers, energy transfer
