As. Dvornikov et al., SPECTROSCOPY AND KINETICS OF PHOTOCHROMIC MATERIALS FOR 3D OPTICAL MEMORY DEVICES, Journal of physical chemistry, 98(27), 1994, pp. 6746-6752
The spectra and kinetics of photochromic molecules have been studied b
y means of two-photon excitation. All intermediate states and species
have been identified and their formation and decay rates, from the pic
osecond to the millisecond range, measured, and the reaction mechanism
has been deduced. The methods and optical system for the utilization
of these molecules in 3D computer memory storage devices are presented
.
