Abstract: A Pb-containing mixed halide, Pb7F12Br2, was synthesized and confirmed by single X-ray diffraction. Its nonlinear optical (NLO) and related properties have been studied systematically for the first time. It shows much wide energy band gap of 4.32 eV with large laser damage threshold (LDT) value of 25 MW·cm-2 that is higher than that of the currently commercialized infrared (IR) NLO material AgGaS2 measured at the same conditions (<5.2 MW·cm-2). Second harmonic generation (SHG) effect test shows that its powders exhibit phase-matching SHG response of about 1.5 times as strong as that of KDP (KH2PO4). Its powders also show good transparence in the region of 0.3~14 μm and exhibit excellent thermal stability with the decomposition temperature up to 650 ℃. Thus, it shows good comprehensive properties. |
