Synthesis and characterization of Fe/Mn co-doped CuCr2O4 ...

Mar 01, 2022 A deep black near-infrared reflectance pigment based on CuCr 2 O 4 doped with Fe and Mn ions was described. The formula of the pigment was CuCr 2-x-y Fe x Mn y O 4.The band gap of pigments decreased from 1.25 eV to 1.00 eV along with the substitution of Fe 3+ and Mn 3+ for Cr 3+ in CuCr 2 O 4.This change originated from the charge transfer of O 2p to Fe …
