Abstract
The new application of YMnO3 as a high near-infrared (NIR) reflective inorganic pigment has been developed. Single-phased perovskite nanocrystalline YMnO3 samples with different average sizes have been synthesized through a polyacrylamide gel route. With the calcination temperature increasing from 700°C to 900°C, the color of the samples is blue-green, and the broad band value decreases from 1.89 to 1.58eV due to the O2p–Mn3d charge-transfer transition. The NIR reflectance and solar reflectance values of corresponding pigmented coating increase from 51.4% to 53.4% and from 23.9% to 32.5%, respectively, which are higher than that of commercially available roofing products of the same color. The prepared YMnO3 pigment can be well served as colored “cool colorant”.
