摘要

本文研究了K(Yb1−x−yTmxHoy)(MoO4)2固溶体的合成条件、晶体生长、相变、形貌和发光光谱。在x + y = 0.01 ~ 0.02范围内，多晶和单晶样品中均有Tm3+和Ho3+离子发出强烈的白光。研究了K - (Yb,Tm,Ho) - mo - o体系的相形成过程，在不同温度下从熔体中生长出K(Yb,Tm,Ho)(MoO4)2和（Yb,Tm,Ho）2Mo3O12单晶。晶体在980 nm光源激发下呈现白光发光。

Synthesis, crystal growth and phase formation in the K–(Yb,Tm,Ho)–Mo–O system

In the present work, the synthesis conditions and crystal growth as well as the phase transitions, morphology, and luminescence spectra of K(Yb_1−x−yTm_xHo_y)(MoO₄)₂ solid solutions have been studied. The intense white emission of Tm³⁺ and Ho³⁺ ions was obtained in polycrystalline and single crystal samples in the range x + y = 0.01–0.02. The phase formation in the K–(Yb,Tm,Ho)–Mo–O system was studied and single crystals of K(Yb,Tm,Ho)(MoO₄)₂ and (Yb,Tm,Ho)₂Mo₃O₁₂ were grown from the melts at different temperatures. The crystals exhibit white-light luminescence excited with a 980 nm source.
