Abstract

In this research, a series of near-infrared (NIR) reflecting nanopigments, based on ZnSxSe1-x(x = 1, 0.75, 0.55, and 0.35), have been synthesized via a coprecipitation reaction and subsequent calcination. Furthermore, their crystal structure, particle morphology, chromatic properties, and NIR reflectance have been investigated in detail; the results show that ZnSxSe1-x pigments have a cubic zinc-blende structure with a space group of F-43m(216), and the pigments’ microstructure presents the agglomerates composed of the spherical particles of different nanosizes. ZnSxSe1-x pigments exhibit not only colors ranging from ivory white to bright yellow but also significant NIR solar reflectance, ranging from 80.96% to 86.65%
