| Abstract: | A new neodymium-doped lanthanum calcium borate (Nd3+:La2CaB8O16, Nd:LCB8) polycrystalline powder was synthe- sized, and a Nd:LCB8 single crystal was grown by top-seeded solution growth (TSSG) method with CaB4O7 as flux. X-ray powder diffraction analysis shows that Nd:LCB8 has the same crystal structure as that of LCB8. The melting point of Nd:LCB8 crystal is about 1 046 ℃. The absorption and fluorescence spectra of Nd:LCB8 were measured. There are several absorption bands in the wavelength range of 300-1000 nm due to the 4f3-4f3 transitions of Nd3+ ions in Nd:LCB8 crystal, and the absorption band at 802 nm corresponding to the output wavelengths of AIGaAs diode lasers has a full-width at half-maximum of 19 nm. There are three emission peaks, around 890, 1 060 and 1 330 rim. The measured fluorescence lifetime is about 75 μs at room temperature. |
