近年来,光盘存储技术蓬勃发展,CD-R光盘,DVD-R光盘应用越来越广泛,蓝光光盘的商品化也已提上日程。在各类可记录光盘中,有机染料作为光盘中的记录介质占有很重要的地位。目前用作光盘记录介质的有机染料种类较多,各有优缺点。其中,花菁染料、四方酸染料和苯乙烯染料具有较高的吸收率、反射率和载噪比,其缺点是光稳定性差,光照后易被单线态氧所氧化。然而,光盘必须有大于十年的工作寿命。因此,在实际应用中要添加单线态氧淬灭剂来抑制染料的光降解反应,提高染料的光稳定性。一.淬灭剂的主要类型单线态氧淬灭剂种类较多,淬灭效果较好的主要有
In recent years, the optical disk storage technology is booming. CD-R discs and DVD-R discs are becoming more and more widely used. The commercialization of Blu-ray discs has also been put on the agenda. Among various types of recordable optical discs, organic dyes play a very important role as recording media in optical discs. Currently used as optical recording media more types of organic dyes, each have their own advantages and disadvantages. Among them, cyanine dyes, tetragonal acid dyes and styrene dyes have high absorption rate, reflectance and carrier to noise ratio, the disadvantage is poor light stability, easy to be singlet oxygen after oxidation. However, the disc must have a working life of more than ten years. Therefore, in practical applications to add singlet oxygen quencher to inhibit the photodegradation of the dye reaction to improve the light stability of the dye. One. The main types of quenching singlet oxygen quenching more species, the better quenching the main
