Embodiment 1

[0014] A mixed powder of ZnO and MnO with an atomic ratio of Mn in the range of 3% was mixed for 3 hours with an agate ball and a jar ball mill to prepare a mixed powder. After the quartz glass is polished on both sides by mechanical polishing, the mixed powder is mixed with alcohol to form a slurry, and evenly coated on the surface of the quartz glass, so that the powder slurry is in full contact with the glass. Put the slurry-coated quartz glass into a heat treatment furnace, heat it to 100°C, and keep it warm for 30 minutes. Continue heating to 1000°C, keep the temperature for 3 hours, and then cool to room temperature with the furnace. The remaining powder was removed, and the heat-treated surface was properly polished, and then the corresponding inspection was carried out. It was found that the surface area had a mosaic structure of nanoparticles, the average particle size was 6 nanometers, and the growth depth was 80 nanometers.

Embodiment 2

[0016] A mixed powder of ZnO and MnO with an atomic ratio of Mn in the range of 7% was mixed for 3 hours with an agate ball and a jar ball mill to prepare a mixed powder. After the quartz glass is polished on both sides by mechanical polishing method, the mixed powder is properly pressed into a block and placed on the quartz glass so that the powder is in full contact with the glass, and then covered with block Zn 1-x mn x Put the O glass into a heat treatment furnace, heat it to 100°C, and keep it warm for 30 minutes. Then continue heating to 1200°C, keep the temperature for 5 hours, and then cool to room temperature with the furnace. Remove Zn from quartz glass 1-x mn x O block, and properly polish the heat-treated surface of the quartz glass, and then do the corresponding inspection.

Embodiment 3

[0018] A mixed powder of ZnO and MnO with an atomic ratio of Mn in the range of 5% was mixed for 3 hours with an agate ball and a jar ball mill to prepare a mixed powder. After the quartz glass is polished on both sides by mechanical polishing, the mixed powder is mixed with alcohol to form a slurry, and evenly coated on the surface of the quartz glass, so that the powder slurry is in full contact with the glass. Put the slurry-coated quartz glass into a heat treatment furnace, heat it to 100°C, and keep it warm for 30 minutes. Continue heating to 1100°C, keep the temperature for 4 hours, and then cool to room temperature with the furnace. The remaining powder was removed, and the heat-treated surface was properly polished, and then the corresponding inspection was carried out. It was found that the surface area produced a nano-particle mosaic structure, the average particle size was 6 nanometers, and the growth depth was 90 nanometers.

Abstract

A heat treating method for preparing the glass able to emit strong blue influorescence from its surface includes such steps as polishing both surfaces of quartz glass, sufficient contact between the polished quartz glass and the mixture of ZnO powder and MnO powder, heating the quartz glass whose surfaces carry said powders to 1000-1200 deg.C, holding the temp for 1-3 hr, and polishing.

Description

technical field [0001] The invention relates to a heat treatment preparation method for surface strong blue fluorescent glass, which belongs to the field of surface nano science and technology and photoelectric new materials. Background technique [0002] Specialty glasses are widely used in construction, solar applications, display technology and high-energy particle detection. Fluorescent glass is a type of special glass, which is mainly used in flat display and high-energy particle detection. There are currently two main preparation methods: one is to add fluorescent impurity centers during the glass incubation process; the other is to deposit a luminescent layer on the surface of the glass through surface coating technology. Both involve extremely complicated process and strict process requirements. For special applications such as fluorescence detection of high-energy charged particles, the receiving surface is required to have a strong fluorescence effect, and the su...
