Two-Photon Absorption Materials for Multi-Layer Optical Data Storage

探索了适用于多层光数据存储的双光子吸收(TPA)材料。这项研究旨在开发可使用工作在660或780 nm附近的半导体激光器激发的固态TPA材料。这些波长用于实际的光学数据存储。在经济、贸易和工业部2007年路线图中，这种波长的高效TPA材料预计将在2015年晚些时候实现。本研究制备的粘土矿物/染料复合材料具有预期的性能。

Two-photon absorption (TPA) materials suitable to multi-layer optical data storage have been explored. This study aimed at the development of solid-state TPA materials excitable using a semi-conductor laser which operates at a wavelength near 660 or 780nm. The wavelengths are used for practical optical data storage. Such efficient TPA materials at the wavelengths were expected to be attained later than 2015 in the 2007 road-map of the Ministry of Economy, Trade and Industry. Clay mineral/dye composites fabricated in this study exhibited the desired properties.
