Abstract
The influence of surrounding gas pressure upon PL spectra of C60 is observed. The relationship between intensity of PL spectra and pressure agrees well with the Langmuir formula of a monomolecular adsorption layer. This phenomenon is attributed to the fact that the disturbance of molecules adsorbed on C60 lowers the symmetry of C60 and reduces the inhibition of the electronic transition, hence influencing PL emission.Keywords
