Solution combustion synthesis of gray-blue Mn-doped YBO3 pigments with high NIR reflectance for energy-saving buildings

Color modulation of cerium sulfide colorant powders through chemical doping engineering

“…Due to their good chemical stability, light resistance, weather resistance, and strong hiding power, inorganic red colorants are widely used in coatings, outdoor displays, building materials, and other fields. [1][2][3][4][5] Red colorants (e.g., CdS 1Àx Se x , Pb 3 O 4 ) are currently widely used, but most contain toxic heavy metals such as lead, chromium, and cadmium. [6][7][8] Therefore, it is urgent to find an inorganic red dye that is safe for the environment and non-toxic.…”

Ion Substitution Strategy toward Spectral Tunability of Environmentally Friendly Rare Earth Sulfide Lattices for Radiative Cooling

“…Pigments are an indispensable presence in life as part of the rich lives of people, and inorganic pigments containing heavy metal ions such as chromium and lead have excellent properties, but their toxicity to the human body cannot be ignored. Due to its features of pigments with no toxicity, strong coloring power, good dispersion, etc. – γ-Ce 2 S 3 as a rare earth sulfide can be used as a colorant in ceramics, plastics, architectural coatings, and other fields, displaying its broad development prospect. – However, H 2 S, CS 2 , and other toxic gases were often used in the synthesis process of γ-Ce 2 S 3 , suggesting the necessity to find a green and environmentally friendly synthesis method.…”
