Novel, brown and yellow inorganic pigments LaFe1-xAlxO3 (x=0, 0.1, 0.3, 0.5, 0.7) with high near-infrared (NIR) reflectance have been prepared by a Sol-Gel method. Replacing Al3+ for Fe3+ in LaFeO3 changed the color from brown to yellow and the band gap increased from 2.46 ev to 2.77 eV due to the quantum confinement effect arising from the small size regime. Moreover, the synthesized pigments and the coatings colored with them possess high NIR solar reflectance in the range of 700-2500 nm. The temperature difference between the pigments we prepared and standard pigments was evaluated in simulating their usage as building roof materials. The thermal and chemical stability of the pigments were also studied. (C) 2014 Elsevier B.V. All rights reserved.
