PEPC sensitization with polymethine dyes: 1. Squarylium dyes of indole row as efficient sensitizers for red region of optical spectrum

Phase hologram recording is based on photoconductivity which appears in polymer molecular semiconductor film being exposed to light [1]. Photocurrent threshold depends on energy gap between valence and conduction bands of a photoconductor (PC). Energy gap of PCs based on poly-N-epoxypropylcarbazole...
