Obtaining and scintillation properties of crystals based on Eu²⁺ doped Ba(Br₀.₉Cl₀.₁)₂ solid solution
Scintillation crystals based on BaBr₂-BaCl₂ solid solution corresponding to minimal melting point in the phase diagram doped with Eu²⁺ (from 0.3 to 3 mol. %) were grown by Bridgman-Stockbarger method. The X-ray luminescence spectra of pure matrix of Ba(Br₀.₉Cl₀.₁)₂ composition includes wide emission...
