“…The occupation of the states leads to a decrease in the absorption and their depletion results in an increase in the absorption. It is worth noting that the position of the specific features in the first region of the modulation spectrum coincides well with the position of the emission bands in the photoluminescence and electroluminescence spectra of PDP [16].…”

“…Somewhat arbitrarily, all the effects can be divided into three large groups. The first group includes electrooptical phenomena; the most interesting of these is the effect of electroluminescence revealed in polymers [16]. The second group comprises unique phenomena of which only one was known previously -the effect of reversible electronic switching of conductivity in an external field.…”

“…It was found that the chem ical structures of (co)polymers influence their mor phology, thermal stability, and luminescent and optical properties [125][126][127][128][129][130][131][132][133][134][135][136][137][138][139][140].…”

“…
Long lasting afterglow emission of UV irradiated samples of some poly(arylene phthalide)s (PAP's) was observed during investigation of spectral and lumines cent physicochemical features of solutions and films of these polymers [1,2]. Thermal treatment of the sam ples after completion of the emission resulted in the re emergence of glow.

“…In addition, UV irradiation of PFP results in the emergence of new long lived absorption centers comprising of polymer chain segments in the triplet state due to intersystem crossing, which facilitate the formation of polymer matrix stabilized radical ions [5]. Radical recombination in PFP films is accompa nied by the emergence of a band at ~500 nm that coin cides with the long wavelength fluorescence band of PFP [1]. The traps stabilized by polymer matrix can be activated by heating, which results in freezing out of molecular mobility of polymer chain segments [6].…”
