Abstract

Here, we designed and prepared a new nano-assembly structure of gold nanorods dispersion medium to improve the data storage life. The surface of gold nanorods was wrapped with a layer of silica shell to enhance the nanorod thermal stability, and then injected into the porous alumina to form a nano-assembly structured film. The experimental results show that gold nanorods are uniformly dispersed in the alumina film, and the optical properties of gold nanorods will not change after heat treatment below 200 °C. It is expected that this film can be used for five-dimensional data storage and greatly improve the thermal stability of stored data.
