- •
A green colored nano-pigment Y2BaCuO5 with impressive NIR reflectance (61% at 1100 nm) was developed.
- •
The UV–vis spectrum exhibits an intense d–d transition associated with CuO5 chromophore between 2.1 and 2.5 eV.
- •
Developed bright green pigments superior to that of commercially available chromium based pigments.
- •
The potential utility of the nano-pigments as “Cool Pigments” was demonstrated by coating on to cement slab and PVC.
