Near-infrared reflecting inorganic pigments based on molybdenum and praseodymium doped yttrium cerate: Synthesis, characterization and optical properties

Vishnu, V S; Reddy, M L P (Elsevier, 2011)

A series of novel environmentally benign near-infrared (NIR) reflecting inorganic pigments based on yttrium cerate doped with metal ions such as Mo(6+) or Pr(4+) have been developed and characterized using XRD. UV-vis-NIR ...
Near-infrared reflecting yellow inorganic pigments based on molybdenum-doped yttrium cerate: Synthesis, characterization, and optical properties

Vishnu, V S; Reddy, M L P (Chemical Society of Japan, 2010)

A new series of yellow inorganic pigments possessing high near-infrared (NIR) reflectance (91-96% at 1100 nm), based on molybdenum-doped yttrium cerate was synthesized by traditional solid-state route. The band gap of the ...
Novel environmentally benign yellow inorganic pigments based on solid solutions of samarium-transition metal mixed oxides

Vishnu, V S; Jose, S; Reddy, M L P (Wiley, 2011)

A new class of environmentally benign yellow inorganic pigments having the general formula Sm6-xW1-yZrxMoyO12+delta (x ranges from 0 to 0.6 and y ranges from 0 to 1) have been synthesized by a simple solid-state route and ...
Synthesis and characterization of environmentally benign calcium-doped Pr2MO2O9 pigments: Applications in coloring of plastics

Giable George; Sandhya Kumari, L; Vishnu, V S; Ananthakumar, S; Reddy, M L P (Elsevier, 2008)

A new class of environmentally benign rare earth pigments of general formula Pr2-xCaxMo2O9-delta(xrangesfrom 0 to 1.0) displaying colors ranging from green to yellow were synthesized by traditional solid-state route, as ...
Synthesis and Characterization of New Environmentally Benign Tantalum-doped Ce0.8Zr0.2O2 Yellow Pigments: Applications in Coloring of Plastics

Vishnu, V S; George, G; Divya, V; Reddy, M L P (Elsevier, 2009)

New inorganic pigments having the general formula Ce1 (xþy)ZrxTayO2þd (x ranges from 0.15 to 0.2 and y ranges from 0 to 0.05) displaying colors ranging from white to yellow have been synthesized by a traditional solid-state ...
The synthesis, characterization and optical properties of silicon and praseodymium doped Y6MoO12 compounds: Environmentally benign inorganic pigments with high NIR reflectance

Giable George; Vishnu, V S; Reddy, M L P (Elsevier, 2011)

Novel, yellow, brown and brick-red colored, near-infrared reflective pigments based on yttrium molybdate doped with metal ions such as Si4+ or Pr4+ are described. Replacing Si4+ for Y3+ in Y6MoO12 changed the color from ...
