Binita Ghosh,Purushottam Chakraborty,Satyabrata Mohapatra,Pushpa Ann Kurian,C. Vijayan,Pranawa C. Deshmukh,Paolo Mazzoldi +6 more
TL;DR: In this article, the formation of copper colloids without thermal annealing can be attributed to the relatively high mobility of copper atoms even at ambient conditions, and the transmittance measurements made by Z-scan technique have revealed saturable absorption signifying the nonlinear optical responses of the metal nanocluster-glass composites.
Journal ArticleDOI
Electronic structure and electrical conduction by polaron hopping mechanism in A2LuTaO6 (A= Ba, Sr, Ca) double perovskite oxides
TL;DR: In this article, an impedance spectroscopy has been applied to explore electrical properties of polycrystalline double perovskite oxides A 2 LuTaO 6 (A = Ba, Sr, Ca, ALT) and A 2 O 3 was detected.
Journal ArticleDOI
Dielectric relaxation and conduction mechanism in Ba2GdTaO6
TL;DR: In this article, the double perovskite oxide barium gadolinium tantalate, Ba2GdTaO6 (BGT) is synthesized by solid-state reaction technique.
Journal ArticleDOI
Dielectric Relaxation and Collective Vibrational Modes of Double-Perovskites A2SmTaO6 (A = Ba, Sr and Ca)
TL;DR: In this article, the crystal structures of double-perovskite oxide A2SmTaO6 series (AST, A = Ba, Sr, Ca) synthesized by solid-state reaction technique are determined from X-ray powder diffraction data.
Journal ArticleDOI
Enhanced nonlinear optical responses in metal-glass nanocomposites
TL;DR: In this paper, the nonlinear refractive index, nonlinear absorption coefficient, the real and imaginary parts of the third-order optical susceptibility have been extracted from Z-Scan and anti-resonant interference nonlinear spectroscopy (ARINS) measurements.
