METHOD FOR MANIPULATING A RARE EARTH CHLORIDE OR BROMIDE OR IODIDE IN A CRUCIBLE COMPRISING CARBON

摘要

The invention concerns a method for manipulating a composition comprising a rare earth halide, in particular in the process of crystal growth from said composition, said crystals being generally of formula AeLnfX(3f+e), wherein: Ln represents one or several rare earth(s); X represents one or several halogen atom(s) selected among Cl, Br or I; and A represents one or several alkaline(s) such as K, Li, Na, Rb or Cs; e and f representing values such that e, capable of being null, is not greater than 2f and f is not less than 1. The invention enables growth of single crystals having remarkable scintillation properties.
