The fluorescence and fluorescence-excitation spectra of adsorbed pyrene on a silica gel surface at low surface coverage have been observed. Pyrene exists as a monomer and dimer in its ground state on a silica gel surface when adsorption occurs from cyclohexane solution. Based on the fluorescence-exc
