Nonlinear absorption of semiconducting microcrystallites under quantum confinement: coexistence of reversible and irreversible effects

摘要

Excitonic processes in CuCl nanospheres of mean radius ranging from 2 to 15 nm embedded in a glass matrix are investigated. Specific features resulting from quantum confinement are analyzed. Correlation between nonlinear-optical and photochemical changes have been revealed. The possibility of application of the same structure in the reversible and irreversible optical memory devices is discussed.
