Brilliant IR Reflecting Yellow Colorants in Rare Earth Double Molybdate Substituted BiVO4 solid solutions for Energy saving applications

Sameera, S; Prabhakar Rao, P; Divya, S; Athira Raj, K V (American Chemical Society, 2015)

Brilliant IR reflecting yellow colorants are developed in rare earth double molybdate substituted BiVO4 solid solutions. Li(0.10)RE(0.10)Ei(0.8)Mo(0.2)V(0.8)O(4) (RE = La, Pr, Sm, Gd, Tb, Dy, Y, Yb and Lu) pigments are ...

Induced oxygen vacancies and their effect on the structural and electrical properties of a fluorite-type CaZrO3–Gd2Zr2O7 system

Vaisakhan Thampi; Prabhakar Rao, P; Radhakrishnan, A N (Royal Society of Chemistry, 2015)

Solid oxide materials were prepared via a solid state reaction route with a stoichiometry composition: x% of CaZrO3 and (100 - x)% of Gd2Zr2O7 (x = 10, 20, 33.3, 40). Powder X-ray diffraction under ambient and high-temperature ...
Novel red phosphors Gd2GaTaO7:Eu3+,Bi3+ for white LED applications

Linda Francis, T; Prabhakar Rao, P; Mahesh, S K; Sreena, T S; Parvathi Babu, S (Springer, 2015)

Novel red phosphor materials Gd2-x-y GaTaO7:xEu(3+),yBi(3+) were prepared using a high temperature solid state reaction route. Crystalline structure, morphology, absorbance and photoluminescence properties were studied ...
Pigments based on terbium-doped yttrium cerate with high NIR reflectance for cool roof and surface coating applications

Athira Raj, K V; Prabhakar Rao, P; Sameera, S; Divya, S (Elsevier, 2015-11)

A new class of pigments: Y2Ce2 xTbxO7 (x ¼ 0, 0.2, 0.4, 0.6, 0.8, and 1.0) were synthesized by a conventional solid state route. The Tb substitution extends the absorption edge to longer wavelengths by introducing an ...
Structural and photoluminescence properties of stannate based displaced pyrochlore-type red phosphors: Ca3-xSn3Nb2O14:xEu(3+)

Sreena, T S; Prabhakar Rao, P; Linda Francis, T; Athira Raj, K V; Parvathi Babu, S (Royal Society of Chemistry, 2015)

New stannate based displaced pyrochlore-type red phosphors, Ca3-xSn3Nb2O14:xEu(3+), were prepared via a conventional solid state method. The influence of partial occupancy of Sn in both A and B sites of the pyrochlore-type ...
