Abstract Neodymium-doped (Nd3+) CsGd(MoO4)2 crystals were grown by the low-thermal-gradient Czochralski technique for the first time. NIR photoluminescence (PL) spectra were measured for Nd3+ doped CsGd(MoO4)2 crystals at 77-300K temperature range. Emission band near 900nm corresponding to 4F3/2→4I9/2 transitions in neodymium-doped CsGd(MoO4)2 crystals and 1060nm band of 4F3/2→4I11/2 transitions were observed. Decay curves were obtained for the energy levels 4F3/2 of Nd3+ in CsGd(MoO4)2 crystals and lifetimes were measured. Decay time constants demonstrate thermal stability with a deviation of about 10μs at 77-300K temperature range and are equal to 157μs at 585nm excitation.

Nd3+-掺杂的CsGd(MoO4)2晶体的光学和近红外发光研究

摘要 首次采用低热梯度直拉技术生长了掺钕 (Nd3+) CsGd(MoO4)2 晶体。在 77-300K 温度范围内测量 Nd3+ 掺杂的 CsGd(MoO4)2 晶体的 NIR 光致发光 (PL) 光谱。900nm 附近的发射带对应于掺钕 CsGd(MoO4)2 晶体中的 4F3/2→4I9/2 跃迁和 4F3/2→4I11/2 跃迁的 1060nm 带。获得了 CsGd(MoO4)2 晶体中 Nd3+ 能级 4F3/2 的衰减曲线，并测量了寿命。衰减时间常数证明了热稳定性，在 77-300K 温度范围内的偏差约为 10μs，在 585nm 激发下等于 157μs。
