X-ray photoelectron and X-ray excited Auger spectra, optical absorption and DC conductivity
of vanadium phosphate glasses containing nickel oxide have been studied as a function of …

The present work reports the frequency, temperature and composition dependence of ac &
dc conductivity, dielectric constant and impedance spectroscopic parameters for glass …

The optical and electron spin resonance (ESR) spectra of barium borate glasses, containing
the oxides of V, Fe and Cu separately and in mixed proportions, have been studied. The …

A long time ago, about 20–25 years ago, when we used to work on materials with small
particles even in the range 4–5 nm, particularly in a magnetic or electronic material, we were …

Semiconducting glasses of the V 2 O 5–NiO–TeO 2 system were prepared by the press-
quenching method and their dc conductivities in the temperature range 300–450 K were …

Abstract The glass sample containing 37.5-mol% Na 2 O, 10-mol% TiO 2, 15-mol% V 2 O 5,
and 37.5-mol% P 2 O 5 was prepared using the melt-quenching process. Nano-crystallized …

Vanadium phosphate glasses containing CuO with the chemical composition [(V2O5) 0.6− x
(P2O5) 0.4 (CuO) x], where x= 0.0, 0.1, 0.2 and 0.3, have been prepared and investigated by …

The electrical resistivities and activation energies for electric conduction in glasses of the
system Na 2 OV 2 O 5-B 2 O 3 with V 2 O 5< 15 mol.%, have been measured. Two types of …

Barium borate glasses containing 0-35 mole% V 2 O 5 were found to be homogeneous.
Optical absorption spectra indicated that only V 4+ of the lower valence states of vanadium …
