Many of the interesting properties that make Ta2O5 a strategic material for current and future applications in chemistry, microelectronics and optics, depend on its structural characteristics. In this work, we use Raman spectroscopy to probe structur

We study the concentration dependence of Raman spectra of MgO doped LiNbO3 crystals. We focus our attention on the width of the E(TO1) phonon located at 153 cm−1, which is used in pure lithium niobate to determine precisely the composition of the c

Low-temperature emission spectra of LN: Cr with a rich Li content display new peaks labelled L3 and L4 at 738 and 745 nm, respectively. Their fluorescence decay time is similar to the one detected in the broad band 4T2 ⇒ 4A2 at 800 nm. We assign L3

The Raman spectrum of has been measured for various scattering configurations in crystals with different compositions. The comparison between spectra recorded for the congruent and the nearly stoichiometric crystals shows significant differences in t

In this work we investigate the iron incorporation in thermally diffused Fe doped LN, by combining two experimental techniques, i.e. micro-Raman spectroscopy and proton induced X rays emission. Our results point out that in substituting for Li, Fe io

We present and discuss the mechanism of incorporation of Mg ions in congruent lithium niobate where we assume the coexistence of both lithium and niobium vacancies induced for charge compensation. This model is supported by the site spectroscopy affo
