abstract
(1996) 2017 SPIE. Organic molecules have been dispersed in polymers and used in 3D memory devices. The time resolved spectra of their transient species and kinetics of the photoinduced reaction have been studied by means of ultrafasttime resolved absorption and emission spectroscopy. The reaction mechanism and rates have been determined andsome photochrome materials have been used successfully to store and access information in 3D format.
