Abstract
The photoluminescence (PL) and amplified spontaneous emission (ASE) spectra of the conjugated polymer [2-methoxy-5-(2'- ethylhexyloxy)-1, 4-phenylenevinylene] (MEH-PPV) is study under different conditions such as thin film and solution, solvent type and concentration. Experiments indicate that aggregation has a pronounced effect on the measured spectra of both the PL and the ASE. In solution form, the ASE emission bandwidth decreases with the increment on concentration as well as a red shift of the ASE peak. For the thin film samples, the ASE spectra show two emission bands corresponding to the emission of the inner and the outer polymer chains. These two emission bands were associated with the gas to crystal effect, previously reported for PL.
