摘要
The subject of the present disclosure is a multilayer nanoparticular, mesoporous structure that has properties of a Bragg reflector or of a unidimensional photonic crystal in the ultraviolet, visible and infrared ranges close to the electromagnetic spectrum. The unidimensional photonic crystal is formed by laminae with different indices of refraction and of a controlled size, made up of nanoparticles, which can be deposited on different types of substrates using a simple and reliable method. The periodic alternating of laminae with different indices of refraction gives rise to a high reflection factor which can easily be observed with the naked eye and can be measured with a spectrophotometer. In contrast to other, dense, reflective structures, the mesoporous structure of this reflector allows the passage of liquids.
