为了达到高密度存储, 关键而有效的方法是获得更短波长的光存储材料. 报道了具有纳米金属-偶氮染料包覆共掺杂结构复合材料的制备及光吸收蓝移现象. 实验发现, 在这种独特结构的复合膜中, 具有存储功能的偶氮染料甲基橙的最大吸收波长比其单独存在于复合膜中蓝移约23 nm, 复合膜的热稳定性提高. 用TEM, SPM, UV-vis, TGA对样品的物理特性进行了表征. 描述了包覆结构的模型, 分析了波长蓝移的机理. 研究结果表明, 具有这种结构的甲基橙有望成为与蓝紫光半导体激光器(GaN)匹配的新一代光存储材料.
In order to achieve high-density storage, a key and effective method is to obtain shorter wavelength optical storage materials.Preparation of nanocomposite with nano-metal-azo dye co-doped structure and blue absorption of light absorption are reported.It is found that, The maximum absorption wavelength of the azo dye methyl orange with storage function in this unique composite membrane is about 23 nm blue-shifted than that of methyl orange alone, and the thermal stability of the composite membrane is improved.Using TEM, SPM , UV-vis, TGA were used to characterize the physical properties of the samples. The model of the cladding structure was described and the mechanism of blue-shift of the wavelength was analyzed. The results show that methyl orange with this structure is expected to be the best- (GaN) match a new generation of optical storage materials.
