Abstract

A crack-free Rb₄Li₂TiOGe₄O₁₂ (RLTG) bulk crystal with dimensions up to 43 × 42 × 27 mm³ was grown by the high-temperature solution method and investigated for luminescence properties under UV and X-ray excitation for the first time. RLTG crystal displays an exceptional bluish-green photoluminescence peaking at 481 nm with a photoluminescence quantum yield 55.81 %. The fluorescence of the RLTG crystal comes from the isolated distorted TiO₅ square pyramids. The light yield of RLTG crystal was measured to be 12,000 photons/MeV under steady-state X-ray excitation, surpassing that of the commercial scintillator Bi₄Ge₃O₁₂ (BGO).

期刊介绍： The journal offers a common reference and publication source for workers engaged in research on the experimental and theoretical aspects of crystal growth and its applications, e.g. in devices. Experimental and theoretical contributions are published in the following fields: theory of nucleation and growth, molecular kinetics and transport phenomena, crystallization in viscous media such as polymers and glasses; crystal growth of metals, minerals, semiconductors, superconductors, magnetics, inorganic, organic and biological substances in bulk or as thin films; molecular beam epitaxy, chemical vapor deposition, growth of III-V and II-VI and other semiconductors; characterization of single crystals by physical and chemical methods; apparatus, instrumentation and techniques for crystal growth, and purification methods; multilayer heterostructures and their characterisation with an emphasis on crystal growth and epitaxial aspects of electronic materials. A special feature of the journal is the periodic inclusion of proceedings of symposia and conferences on relevant aspects of crystal growth.
