摘要
This paper reports the growth, X-ray diffraction and spectroscopy of Nd3+:Sr3Gd2(BO3)4 crystal. A Nd3+:Sr3Gd2(BO3)4 crystal with dimensions of φ20 × 45 mm3 has been grown by the Czochralski method. Nd3+:Sr3Gd2(BO3)4 crystal belongs to the orthorhombic system, space group Pnma (D2h) with a = 0.7401, b = 1.604 and c = 0.8755 nm. The absorption and emission spectra of Nd3+:Sr3Gd2(BO3)4 were investigated. The absorption cross section oa is 3.11 × 10^-20cm2 at 808 nm. The absorption transition at 808 nm has an FWHM of 14 nm. The luminescence lifetime τf is 51.7 μs. The emission cross section oc at 1064 nm wavelength is 1.09 × 10^-19 cm2.
