COLOURED SOLAR REFLECTING COATINGS PREPARED BY THE SOL-GEL PROCESS

摘要

Class coloured solar reflecting films with double layer coatings of SiO_2-MnOm-NpOq (M, N = Fe, Co, Cr) and TiO_2 have been prepared on colorless float glasses by the Sol-gel route using dip-coating technique.Optical properties of coatings have been investigated by spetrophotometric technique. The structures of mutilayer coatings and valence of transition metal ions in final films have been studied by use of X-ray diffraction and SEM-EDS.
