Název v původním jazyce

Novel method of search for transparent optical materials with extremely high melting point

Popis výsledku v původním jazyce

We propose a novel crystal growth method, “Core Heating (CH) Method”, which is suitable for a search of novel materials with extremely high melting points above the melting (softening) point of an Ir crucible. As a feasibility test of the novel CH method, we fabricated the conventional material Ce:YAG, with a melting point of ∼1970 °C, because this material can be grown by the conventional melt growth technique like the micropulling down (mPD) method for the comparison. We compared scintillation properties for Ce:YAG prepared by the CH and mPD methods in order to find if the CH method can be applied to the material search. The crystals grown by both methods showed the YAG single-phase, and almost all their optical and scintillation properties of them were comparable for both samples. Particularly, the light output of Ce:YAG crystal grown by the CH method (20,000 ± 1,000 photons/MeV) was similar to that of the sample grown by the mPD method.
