Molecular formula: Ho2O3 Molecular weight: 377.86
Description: Nano holmium oxide is a light yellow crystalline powder, which belongs to the isoaxial scandium oxide structure. Insoluble in water, soluble in acid. The preparation method of nanometer holmium oxide is that holmium oxide precursor is prepared with HoCl3 as raw material and polyvinyl alcohol as dispersant by ammonium bicarbonate precipitation process, then methanol is added, and it is heated to decompose, the holmium oxide Ho2O3 obtained is crushed and screened to obtain nanometer holmium oxide.

Used: Used in the manufacture of additives of Metal Halogen Lamp and Yttrium iron or yttrium aluminum garnet. The main uses of nanometer holmium oxide are as follows: 1. It is used as additive of metal halide lamp. Metal halide lamp is a kind of gas discharge lamp, which is developed on the basis of high pressure mercury lamp. Its characteristic is that there are various rare earth halides in the bulb. At present, rare earth iodide is mainly used, which emits different spectral line light color in gas discharge. The working substance used in the nano Ho lamp is nano holmium oxide iodide, which can obtain higher metal atom concentration in the arc region, thus greatly improving the radiation efficiency. 2. Nano holmium oxide can be used as yttrium iron aluminum garnet (Ho:YAG) to emit 2μm laser. The absorption rate of human tissue to 2μm laser is high, almost three orders of magnitude higher than that of Ho:YAG. Therefore, when the Ho:YAG laser is used for medical operation, not only the efficiency and accuracy of the operation can be improved, but also the thermal damage area can be reduced to a smaller area. The free beam generated by nano holmium oxide crystal can eliminate fat without generating too much heat, thus reducing the thermal damage caused by healthy tissues. It is reported that the treatment of glaucoma with nano holmium oxide laser in the United States can reduce the pain of surgery. 3. The optical communication devices such as fiber laser, fiber amplifier and fiber sensor can be made by using nano holmium oxide doped fiber.
