【Abstract】 Doping CuO in KLN and using Czochralski method to grow Cu∶KLN crystal. The composition of Cu∶KLN crystal and the composition dependence on the growrh rate, using field cooling method to pole Cu∶KLN crystal, and using the mixer of HF and HNO 3 to corrode the poled plate. The infrared spectra of Cu∶KLN was measured and the Cu 2+ site in Cu∶KLN crystal was studied. The Raman spectra was measured and the structure of Cu∶KLN crystal was studied. The cause of cracking and losing clear in crystal was studied and the way to overcome these questions was gained. Cu∶KLN crystal with 6×8×3(mm 3) size was grown.更多还原
