Abstract

The role of the compositional modulation at nano-scale dimensions (similar to 2-10 nm) in the enhancement of optical recording parameters in nanomultilayers, which contain Sb as active, optical absorbing and diffusing layers and As2S3 as barrier (matrix) layers was investigated. Comparison was made with single homogeneous layers made of ternary (As2S3)(x)Sb1-x glasses and co-deposited from Sb and As2S3. It was shown that essential increase of the recording efficiency, sensitivity of the bleaching process, broadening of its spectral range occurs due to the stimulated interdiffusion of adjacent components in Sb/As2S3 nanomultilayers with optimized Sb layer thickness.
