摘　　要：信息技术的发展要求存储器件必须具备超高存储密度、超快存取速率以及长存储寿命。而目前普遍应用的光数据存储的存储密度已经接近其物理极限。双光子吸收技术以其强的穿透能力和高的空间分辨率能够实现多层存储 ,存储密度高达 10 12 bits cm3 ,但能否开发出具有大的双光子吸收截面的材料成为制约其发展的一个重要因素。本文在综述近年来双光子吸收有机材料研究的基础上 ,介绍了双光子吸收有机材料在三维数字光存储中应用研究的最新进展。The development of information technique requires that a data storage device must possess the character of ultra-high density, ultra-fast transfer rate and longer storage longevity. At present, the storage density of the most popular optical data storage is reaching the physics limit. Because of its strong penetration and high resolution, two-photon absorption can be applied to multi-layer optical data storage, and the bit density of which can reach as large as 10 12 bits/cm 3. Now the key problem is to develop materials that have big two-photon absorption cross-sections. In this paper, progress in two-photon-absorbed organic materials is reviewed, and the new development of three-dimensional optical data storage based-on these materials is introduced.
