Optical storage performance of cyanine-doped ormosil films

Cyanine dye which is now widely used as recording media in write-once optical disks was doped into ormosil precursor solution via sol-gel method. The dye-doped ormosil films were prepared by spin coating process. Optical recording experiment was performed on the sol-gel films. More than 45 dB of carrier to noise ratio was obtained in the sol-gel films under normal writing/reading conditions of recordable-CD. This shows the ability of the ormosil as the host of the dye for optical disks.
