| 英文摘要 | Transparent ceramics with good electrical performance have recently drawn broad interest as promising multifunctional materials. Here, we report that a superior transmittance (T = 75 % at 2000 nm) and good piezoelectricity (d(33) similar to 150 pC/N) can be simultaneously realized in 0.93K(0.5)Na(0.5)NbO(3)-0.07SrZrO(3) (KNN-SZ) ceramics by Li2O regulation. The effect of Li 2 0 regulation has two parts: first, the presence of Li2O facilitates the grain growth of KNN-SZ, considering that it melts at a relatively low temperature as a proper sintering aid; second, the introduced Li(+ )causes local lattice distortion, resulting in the coexistence of orthogonal and tetragonal (O-T) phases. The enlarged grains reduce the light scattering by grain boundaries for a higher optical transmittance; meanwhile, large grains stand as a prerequisite for the macroscopic domain structure favoured for decent piezoelectricity, which could also be partly caused by the coexistence of O-T phases. We believe that these findings might make KNN-based ceramics a preferable candidate for optoelectronic devices. |
