Abstract
A black IR reflective or transmissive pigment from which LiDAR responsive black coatings can be formed where the pigment displays a Blackness Mvalue similar to non-IR reflective carbon black. The CuO particles display small crystallites of less than 18 nm and an (−111)/(111) reflectance intensity ratio of less than 1.2. A method of forming the CuO particles includes precipitation of CuCO3 or CuCO/Cu(OH)using an alkali carbonate as a precipitant and calcining the precipitate at about 300° C. to about 400° C.
