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 ...
Influence of (LiLa) 1/2MoO4 substitution on the pigmentary properties of BiVO4

Sameera, S; Prabhakar Rao, P; Vineetha James; Divya, S; Athira Raj, K V (Elsevier, 2014-05)

A new series of yellow pigments of the formula [(Li0.5La0.5)x Bi1 x][Mox V1 x]O4 (x ¼ 0,0.1, 0.2, 0.3,0.4, 0.5) were prepared via a solid state method. The structural, morphological and colour characteristics of the ...
Pigments based on terbium-doped yttrium cerate with high NIR reflectance for cool roof and surface coating applications

Athira Raj, K V; Prabhar 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 ...

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 ...
Probing structural variation and multifunctionality in niobium doped bismuth vanadate materials

Sameera, S; Prabhakar Rao, P; Vineetha James; Athira Raj, K V; Chitradevi, G R; Sandhyakumari, L (Royal Society of Chemistry, 2014)

Multifunctional materials are developed in BiV1-xNbxO4 solid solutions via structural variations. A citrate gel route has been employed to synthesize these materials followed by calcination at various temperatures leading ...
Remarkable changes in the photoluminescent properties of Y2Ce2O7:Eu(3+) red phosphors through modification of the cerium oxidation states and oxygen vacancy ordering

Athira Raj, K V; Prabhakar Rao, P; Sreena, T S; Sameera, S; Vineetha James; Renju, U A (Royal Society of Chemistry, 2014)

A new series of red phosphors based on Eu(3+)-doped yttrium cerate [Y1.9Ce2O7:0.1Eu(3+), Y2Ce1.9O7:0.1Eu(3+) and Y2Ce2-xO7:xEu(3+) (x = 0.05, 0.10, 0.15, 0.20, 0.25 and 0.50)] was prepared via a conventional solid-state ...
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 ...
