This study describes the ability to use the melt-level control for stabilization of the crystallization rate during NaI crystal growth by the VGF technique with a skull layer. It is shown that a conventional linear decrease of the heater temperature leads to a nonuniform crystallization rate and deterioration of crystal quality. A method and algorithm of temperature control for the stabilization of the crystallization rate during crystal growth is proposed. The series of growth experiments with NaI(Tl) crystals proved the efficiency of this approach and ability to obtain scintillators with high registration efficiency, about 6.3% energy resolution for a 137 Cs (662 keV) source.

Halide scintillators have been playing a crucial role in the detection of ionizing radiation since the discovery of scintillation in NaI:Tl in 1948. The discovery of NaI:Tl motivated the research and development (R&D) of halide scintillators, resulting in the development of CsI:Tl, CsI:Na, CaF2:Eu, etc. Later, the R&D shifted toward oxide materials due to their high mechanical and chemical stability, good scintillation properties, and relative ease of bulk single‐crystal growth. However, the development in crystal growth technology allows for the growth of high‐quality single crystals of hygroscopic and mechanically fragile materials including SrI2 and LaBr3. Scintillators based on these materials exhibit excellent performance and push the limits of inorganic scintillators. These results motivate intense research of a large variety of halide‐based scintillators. Moreover, materials based on lead halide perovskites find applications in the fields of photovoltaics, solid‐state lighting, and lasers. The first studies show also the significant potential of lead halide perovskites as ultrafast scintillators in the form of nanocrystals. The purpose of this review is to summarize the R&D in the field of halide scintillators during the last decade and highlight perspectives for future development.
