Abstract
Selective laser excitation of the luminescence of a thin film of the r r-conjugated polymer poly(p-phenylene) at room temperature is achieved . Monochromatic excitation is selective only for excitation in the lon g-wavelength wing of the absorption spectrum. This is manifested as a shift of the luminescence spectrum with excitation frequency. The expe rimental results are interpreted on the basis of model calculations.
