在刚刚于日本东京结束的2008年光存储技术国际学会上(ISOM),有人提出“光存储最大的问题是应用而不是技术。”光存储技术已历经了三代,继CD、DVD及蓝光光盘之后,第4代光盘最大的问题则是应用。Flash闪存在经历多年后,已经成为用户在日常存储时所用到的主要工具,而数字音乐和视频普及也在慢慢侵蚀原有的光存储领域,如果没有一个很好的切入点,蓝光将成为光存储的“末代皇帝”。 相似文献

Long persistent and photo‐stimulated luminescence in Pr3+‐doped layered perovskite phosphor for optical data storage 下载免费PDF全文

As the time for big data is coming, the demand for data's storage density and capacity exerts explosive growth. However, traditional optical storage is hard to get rid of the bottleneck of optical diffraction limit. The persistent luminescence materials could be used for optical data storage based on the photon trapping and de‐trapping mode. Herein the performance of thermoluminescence (TL), photo‐stimulated luminescence, and photoluminescence of Pr3+‐doped Ca4Ti3O10 were studied in order to explore the optical storage property of this material. The TL glow curves show that the deep‐trap in Ca4Ti3O10:0.01Pr3+, Y3+ has a narrow distribution from 0.9 to 0.98 eV, which is qualified for maintaining the recorded data at RT for a long duration time. NIR photo‐stimulated red persistent luminescence (NIR‐to‐red mode) as presented in the Y‐containing Ca4Ti3O10:Pr3+ phosphor could be a promising technique for optical data storage. 相似文献

The fine optical structures in wing scales of Trogonoptera brookiana, a tropical butterfly exhibiting efficient light trapping effect, were carefully examined and the reflectivity was measured using reflectance spectrometry. The optimized 3D configuration of the coupling structure was determined using SEM and TEM data, and the light trapping mechanism of butterfly scales was studied. It is found that the front and back sides of butterfly wings possess different light trapping structures, but both can significantly increase the optical path and thus result in almost total absorption of all incident light. An optical model was created to check the properties of this light trapping structure. The simulated reflectance spectra are in concordance with the experimental ones. The results reliably confirm that these structures induce efficient light trapping effect. This functional "biomimetic structure" would have a potential value in wide engineering and optical applications. 相似文献

Nanostructured glass surfaces enable new and innovative applications for glass substrates. These nanostructures enable trapping as well as extraction of light. They affect the propagation of light such that it scatters and is trapped or extracted based on the index of the propagation media. The diffusive scattering component as opposed to the specular component is what enables the trapping and extraction. Often smooth surfaces are required for growing semiconductor thin films. Scattering sites beneath these surfaces can significantly enhance the optical performance of these films. Example devices utilizing these substrates include organic light-emitting diodes (OLED) displays, OLED lighting components, and microelectromechanical systems reflective displays. We demonstrate methods to fabricate these substrates using nanoparticle deposition processes. Important parameters of these nanoparticles and their agglomerates include both size and refractive index. We characterize these substrates using atomic force microscopy and scanning electron microscopy microscopy, and we simulate their optical properties using optical scattering models. 相似文献
