The fluorescence quantum distributions, quantum yields, degrees of polarisation, and stimulated emission cross-section spectra of four para-phenylene vinylene and two para-phenylene ethynylene luminescent polymers were determined. Neat luminescent polymer films and polystyrene films doped with luminescent polymers were investigated. The fluorescence spectroscopic data analysis accounted for fluorescence absorption and reemission in thin films. The fluorescence spectroscopic behaviour of the solid thin films on fused silica substrates was compared with the corresponding behaviour of the luminescent polymers dissolved in liquid tetrahydrofuran.
