Synthesis and Nonlinear Electro-Optical Properties of Zn4B6O13

This paper reports the results of the investigation of second order optical nonlinearity, as well as the polarization nonlinear behavior of Zn4B6O13. For experiments samples were prepared by thermal treatment of glass tapes and solid state synthesis. The tapes were obtained by a rapid melt quenching technique. The thermal processes in the glass tapes were investigated by differential thermal analysis. The synthesized materials were studied by X-ray diffraction. For the sample thermally treated at 710°C for 18 h, the remnant polarization up to 0.04 μC/cm2 was measured under an electric field of 49 kV/cm. It was shown that the second harmonic generation intensity of Zn4B6O13 is 1.9 times higher than that of the well-known optical material KH2PO4.
