Abstract: PURPOSE:To obtain a detector used for high-power infrared laser beams and having excellent durability and emission characteristics. CONSTITUTION:The detector is prepared by binding a powder of a phosphor which converts infrared laser beams into visible light and comprises a fluoride based on lead fluoride in which erbium fluoride and ytterbium fluoride are dissolved to form a solid solution with a glassy substrate. This detector shows a high damage threshold value even with respect to YAG laser beams, does not suffer from damage of phosphor by YAG laser beams, and has high reliability. When compared with conventional detectors, it has a remarkable high emission intensity and can sharply detect YAG laser beams.

Abstract: PURPOSE:To obtain a highly practical infrared detecting body which can stably maintain its light emitting property by preventing the deterioration of a light emitting body composed mainly of a halogenated rare-earth element caused by oxygen and water by sealing the light emitting body with a non-transmissive coating material. CONSTITUTION:The title detecting body is composed of a substrate 10 made of such a non-transmissive material, such as a ceramic, etc., that does not transmit oxygen and water, light emitting substrate 20 which is put in the recessed section 11 of the substrate 10 and composed mainly of a halogenated rare-earth element, and transparent plate 30 which seals the section 11 and is made of quartz glass, etc. The members 11, 12, and 13 are airtightly joined to each other with a bonding agent manufactured from an epoxy resin, low-melting point metal, low-melting point glass, etc., so that no oxygen nor water can intrude among the members 11, 12, and 13 through gaps. Since the periphery of the light emitting substance 20 is sealed with the substrate 10 and plate 30, the substance 20 can obtain the excellent light emitting characteristic of the halogenated rare-earth element and, at the same time, can be stabilized against oxygen and water. Therefore, the light emitting efficiency of the substance 20 does not deteriorate even when the substance 20 is used for a long period and a highly reliable infrared detecting effect can be obtained.
