Abstract
Optical absorption, photoluminescence and Raman spectra of poly(p-phen ylene vinylene) have been recorded as a function of pressure to 50 kba r. Both absorption and emission spectra are observed to red shift with pressure. The photoluminescence spectrum is observed to decrease in i ntegrated intensity and lose vibronic structure with increasing pressu re. Possible explanations of the observed results are discussed. In pa rticular the possible role of intermolecular effects is highlighted. C opyright (C) 1996 Elsevier Science Ltd.
