In the present study, glasses with composition (80-X) Γ B 2 O 3 Γ XBi 2 O 3 Γ 20Fe 2 O 3 (X ΒΌ 10, 15 and 20 mol%) have been prepared by the conventional melt quenching technique. The glassy state of the samples is characterized using DTA and X-ray diffraction. The infrared spectra of these glasses a
a b s t r a c t 3-mol% Y 2 O 3 and 0.3 to 3-mol % Cr 2 O 3 co-doped ZrO 2 nanopowders were synthesized using coprecipitation technique and investigated by terms of X-ray diffraction, transmission electron microscopy and X-ray photoelectron spectroscopy. Structural analysis shows no significant impac
