Chromogenic Materials in Optical Filters for Smart Windows

Abstract

Grating optical chromogenic filter provides angular-selective transmission attenuating direct sunlight and transmitting diffused light. Such a smart window demonstrates more comfortable daylight compared to conventional chromogenic smart window.

Effective medium theory and its limitations for the description of MoO3 films doped with nanoparticles

“…Description of the optical properties of transitions metal oxides (TMOs) thin films doped with plasmonic resonant nanoparticles (NPs) has become very important topic nowadays [1][2][3][4][5]. Is well known that these materials are called 'smart materials' due to their diverse applications as photocatalytic material, chromogenic material, or even as an absorbent layer in solar cells, to mention some of them [6][7][8][9][10][11][12]. This work aims to predict the behavior of TMOs doped with resonant NPs when they are interacting with light using well-known theoretical models.…”
