Optical Memory Storage Material - Cyanine Dyes Mixture and Preparation    

Cyanine dyes mixture employed as optical recording media.

Overview

An inexpensive optical storage medium, smaller in size, with higher storage density. The technology is thermally stable for laser writing, plus soluble in organic solvent for spin coating.

The applications for this type of organic dye include: non-linear optical device, recording and displaying of optical disk data, photo-resist, sensor and indicator for heat, light, and electron, during the transfer and storage of energy, medicine and biology. The cyanine dyes mixture exhibits high absorption coefficient in the infrared region, implying the cyanine dye has high recording sensitivity and signal to noise ratio value. As a result, the cyanine dyes mixture is perfect optical memory storage material.

Primary Application of the Technology

Optical memory storage material
