Abstract

The invention relates to a preparation method of a transition metal microcrystal-doped chalcogenide glass composite material. The method comprises the following steps: (1) preparing a TM<2+>: ZnX material (wherein TM<2+> is a transition metal ion, and X is S or Se): putting TMX powder and ZnX powder into a ball mill, fully and evenly mixing, putting the evenly mixed powder into a smelting furnace, and carrying out heat preservation at the temperature of 850-1100 DEG C for 72-168 hours to obtain the TM<2+>: ZnX material; (2) putting the TM<2+>: ZnX material and chalcogenide glass into the ball mill according to a certain mass proportion, and fully grinding to prepare evenly mixed powder; (3) putting the mixed powder into a quartz tube, vacuumizing the quartz tube, sealing the vacuumized quartz tube, putting the sealed quartz tube into the smelting furnace, and carrying out heat preservation at the temperature of 270-400 DEG C for 2-20 hours to obtain the TM<2+>: ZnX-doped chalcogenide glass composite material. The composite material prepared by the invention is stable in thermal property and high in conversion efficiency, and is excellent in intermediate infrared fluorescence emission, thus providing a new working medium material for development of an intermediate infrared laser.

Description

technical field [0001] The invention belongs to the field of photoelectric functional materials, in particular to a transition metal crystallite-doped chalcogenide glass composite material and a preparation method thereof. Background technique [0002] Mid-infrared lasers with operating wavelengths in the range of 2-5 μm have special applications in many fields. Since this band is in the "transparent window" of the atmosphere, it can be widely used in lidar, laser ranging and atmospheric communication. Utilizing the strong absorption characteristics of water molecules near 3 μm, a new generation of laser surgery system can be developed, which has the advantages of rapid blood coagulation and small surgical wounds. In addition, many harmful substances have abundant absorption peaks in the mid-infrared band, so they can be widely used in the field of environmental monitoring. In the military, since the monitoring band of the strategic missile defense system is in the mid-inf...
