Process for producing a lithium borate thermoluminescent and fluorescent substance

摘要

A process for producing a lithium borate thermoluminescent and fluorescent substance containing lithium borate as its main component which comprises heat-treating a mixture of Li2B4O7 powder and an activator element compound at a temperature under and neighboring the melting point of Li2B4O7, to provide a highly sensitive fluorescent substance which has good adherence to the substrate of a dosimeter.
