| 英文摘要 | Optical properties of < 001 > -oriented pure (K0.4Na0.6)NbO3 (KNN) and 0.5 wtWo Mn-doped KNN (Mn-KNN) single crystals were studied. The refractive indices (n) of both crystals exhibited a normal dispersion behavior in the wavelength range of 300 -1100 nm. The modified Sellmeier dispersion equations for n were obtained by least-squares fit. In addition, Sellmeier coefficients were determined by single-oscillator dispersion relation, which related to energy band structures of crystals. Compared with KNN, a decrease about 10 % in transmittance (over 350 nm) was observed in Mn-KNN due to the losses resulting from the increase of domain wall density. Furthermore, a 20 nm blue-shift in the absorption edge was observed for Mn-KNN. Based on Tauc equation, the band gap energies of 3.26 and 3.42 eV were obtained for KNN and Mn-KNN, respectively. The increase of band gap energy in Mn-KNN was attributed to the distortion of BO6 octahedron building block caused by Mn2+ occupying the B-site. |
