摘要: Abstract Ecological inorganic blue pigments Sr1-xRExCuSi4O10+δ (RE = Pr, Nd, Sm, x ranges from 0 to 0.5) with high near-infrared reflectance were synthesized via sol-gel method. The characterized scanning electron microscopy, UV-vis-NIR diffuse spectroscopy and the Commission Internationale de l’Eclairage 1976 L*a*b* colorimetric After annealed at 900 °C, SrCuSi4O10 pigment samples exhibited solar of 62.64% relative intense color. spectra different rare earth ions doped presented various fluctuations due configurational electric dipole transitions. incorporation can promote pigments. When adding amount Pr, Nd was 20%, 40% 10%, reached optimal value 72.00%, 68.54%, 68.67%, respectively, which are expected be promising candidates as environmentally benign cool
