Problems solved by technology

[0004] The band gap structure of photonic crystals is the most important characteristic, and it is also the basis for the application and development of photonic crystals. The energy loss in the forbidden band of photonic crystals with multilayer film structure is low, but the forbidden band width is limited, and a wide full-angle height appears. Reflection is difficult; compared with such photonic crystals, metal materials have strong reflectivity in any incident direction in a wide frequency range, but absorption leads to greater energy loss; due to most materials There is serious absorption in the band below the visible light, and there are few studies; but because of the potential application prospects, it has become an important research topic

Abstract

The invention relates to a preparation method of a photonic crystal multilayer film. Aiming at application state of the photonic crystal to optical materials, an electrically conductive glass is used as a substrate, and titanium oxide and copper are used as films; TiO2 films and Cu films are sputtered on the substrate through magnetron sputtering; the TiO2 film and the Cu film alternatively arranged form a 14-layer multilayer film structure; then the multilayer film are treated with low temperature tempering to increase physical properties and mechanical properties of the multilayer film. Thepreparation method employs an advanced and rigorous technology with detailed and accurate technical parameters; the product has good quality, high purity and good optical performance; therefore, provided is an ideal preparation method of the photonic crystal multilayer film.

Description

technical field [0001] The invention relates to a method for preparing a photonic crystal multilayer film, which belongs to the technical field of preparation and application of optical materials. Background technique [0002] Photonic crystal is a new optical material that has appeared in recent years.
