We performed selective laser excitation of fluorescence of thin films of poly( p -phenylene) (PPP) at room and liquid helium temperatures. Monochromatic laser excitation becomes selective upon excitation below a threshold frequency of 22 400 cm −1

Selective laser excitation of the luminescence of a thin film of the π-conjugated polymer poly(p-phenylene) at room temperature is achieved. Monochromatic excitation is selective only for excitation in the long-wavelength wing of the absorption spec

J-aggregates of tiacarbocyanine derivative are investigated in frozen solution at low temperatures by optical spectroscopy and spectral hole burning. It is found that absorption and luminescence bands have inhomogeneous widths of 220 and 130 cm-1 at

Porphyrins are used as photosensitizers for diagnosis and photodynamic therapy of cancer [1]. The photodynamic therapy is based on a selective retention of porphyrins by the tumoral tissue and on a light-induced damage of cell membranes mediated by t

Selectively excited room-temperature luminescence spectra are reported for thin films of poly(p-phenylene) (PPP) deposited onto quartz substrata. The spectra exhibit a localization threshold in the low-energy tail of the luminescence excitation band
