ANOTACE

V současné době se stále hledají materiály pro detekci termálních neutronů, které by byly chemicky stabilní, odolné vůči radiaci a nebyly citlivé na vlhkost. Oxidy s obsahem lithia nebo boru jsou jednou z možností pro toto použití. Pro testování byla zvolena jedna z fází pseudobinárního systému Li2O–Al2O3: LiAl5O8 a dopování kationty vanadu. Cílem je zmapovat vlastnosti tohoto dopovaného systému s ohledem na fázovou a tepelnou stabilitu matrice a optické charakteristiky dopovaných iontů vanadu.

ANNOTATION

Currently, the research focuses on materials for thermal neutrons detection that would be chemically stable, radiation resistant and moisture insensitive. Possible materials for this application are oxides containing lithium or boron. For testing, one phase from the pseudobinary system Li2O–Al2O3 was selected, namely LiAl5O8 doped with vanadium cations. The aim is to survey the properties of this doped system in terms of phase and thermal stability of the matrix and optical characteristics of the doped vanadium ions.
