“…It is observed that variation of ln with −1/4 is a straight line as depicted in inset of Figure 12. The linear dependence in our case confirms the presence of hopping type conduction in given temperature range [29][30][31]. Moreover, the obtained value of Δ is almost equal to half of the optical energy band gap (1.78 eV), confirming the correlation between thermally activated charge carriers with localized free-carrier response.…”

We have investigated the optical and electrical properties of polycrystalline DyMn2O5synthesized by sol-gel method. Analysis of the reflectivity spectrum has led to the observation of 18 infrared (IR) active phonon modes out of 36 predicted ones. We discuss the results in terms of different phonon bands originated as a result of atomic vibrations. Moreover, the optical energy band gap ofEg(OC)~1.78 eV has been estimated from optical conductivity(σ1(ω))spectrum. The energy band gap and optical transitions were also determined from UV-visible absorption spectrum and band gap ofEg(UV)~1.57 eV was estimated. Moreover, DC electrical resistivity shows the p-type polaronic conduction above room temperature.
