For the last 75 years several studies have been reporting on the physical properties of
niobium oxides, but there is still many contradictory, inconsistent and insufficient information …

We report diffuse reflectivity measurements in InNbO4, ScNbO4, YNbO4, and eight rare-
earth niobates. A comparison with established values of the bandgap of InNbO4 and …

The Laser Floating Zone (LFZ) technique, also known as Laser-Heated Pedestal Growth
(LHPG), has been developed throughout the last several decades as a simple, fast, and …

In this work, RENbO4 (RE= Y, La, Nd, Sm, Gd, Dy, Yb) ceramics with low density, low
Young's modulus, low thermal conductivity, and high thermal expansion have been …

Zn3 (Nb1− xTax) 2O8 (x= 0.02–0.10) ceramics were prepared via a solid-state reaction route
and the dependence of their microwave dielectric properties on their structural …

Eu-doped bismuth-based Bi1. 5 M 0.4 Mg0. 5Nb1. 5O7− δ (M= Li and Na) pyrochlores were
synthesized by the organic–inorganic precursor combustion technique. The study examined …

This work reports the photoluminescence (PL) properties at room temperature for PrNbO 4
and EuNbO 4 orthoniobates synthesized by solid-state reaction. An accurate colorimetric …

In the present work, we report on a comprehensive study of crystallization, structure and
optical spectroscopy of transparent glass–ceramics with (Eu 3+, Yb 3+): YNbO 4 …

Gadolinium orthoniobate ceramics, GdNbO 4, were prepared by a conventional solid state
reaction method. The synthesized sample was characterized by means of X-ray diffraction …

Raman and luminescence studies on the phase transition of europium orthoniobates
(EuNbO 4) under high pressure were performed. The pressure dependent Raman spectra …
