TO ELECTROCHROMIC AND CHROMOGENIC TECHNOLOGIES The basic property of a chromogenic material is that it exhibits a large change in optical properties upon a change in either electrical field, charge, light intensity, spectral composition, or temperature. This optical change results in a transformation from a highly transmitting state to a partly reflecting or absorbing state, either totally or partly over the visible and solar spectrum. The physical phenomena of interest for optical switching processes can be classified in one of two categories: electrically activated or non-electrically activated. These types are shown in Table 1 |
