Photoluminescence of organo-polysilane is investigated. A comparison is made between the spectra of two kinds of organo-polysilane: methyl-propyl-polysilane and methyl-phenyl-polysilane. A sharp peaked luminescence spectrum in the ultraviolet region is observed in both materials. An additional broad visible luminescence exists in methyl-phenyl-polysilane. These features are discussed using the band calculation results. The half-width of ultraviolet luminescence exhibits strong temperature dependence in spite of a slight Stokes shift.
