REVERSE SATURABLE ABSORPTION SENSITIZERS FOR OPTICAL DATA STORAGE MEDIA AND METHODS FOR USE

摘要

PROBLEM TO BE SOLVED: To provide holographic storage media for optical data storage which can improve sensitivity.;SOLUTION: Disposed within a polymer matrix is a reactant capable of undergoing a modification that alters the refractive index of the composition upon receiving an energy transfer from an excited sensitizer. A non-linear sensitizer is also disposed within the polymer matrix, and the sensitizer includes a metal-substituted subphthalocyanine (M-sub-PC) reverse saturable absorber configured to become excited upon exposure to light beyond an intensity threshold at approximately 405 nm and configured to transfer energy to the reactant.;COPYRIGHT: (C)2013,JPO&INPIT
