找到了合成的物理化学条件，并使用Bridgman技术生长了含有Nd 3+离子的三方GdF 3-CaF 2晶体。详细研究了它们的光谱强度特性。确定了4F 3/2态的歧管间发光分支比和跃迁截面。研究了4F 3/2→ 4 I11/2通道中10495 nm波长的室温受激辐射。
Physical‐chemical conditions of synthesis are found and trigonal GdF3‐CaF2crystals with Nd3+ions are grown using the Bridgman technique. Detailed investigations are made of their spectroscopic intensity characteristics. Intermanifold luminescence branching ratios from the4F3/2state and transition cross‐sections are determined. A room temperature stimulated emission at 10495 Å wavelength in the4F3/2→4I11/2channel is excited and studied.
