Holmium Oxide Nanoparticle Ho2O3 CAS 12055-62-8 For Metal Halogen Lamp Additives

Nanometer holmium oxide (Ho₂O₃) is a rare earth material with good crystal shape, good dispersion and high transparency. Its large specific surface area makes it suitable for coating materials and catalysts. Nano-holmium oxide can be used to make specially colored glass, and can also be used as an additive to yttrium iron or yttrium aluminum garnets. In addition, it is used as a standard for spectrometer calibration, as well as for the manufacture of new light sources, dysprosium-holmium lamps. In the laser field, nano-holmium oxide can be used for optical communication devices such as fiber lasers, fiber amplifiers and fiber sensors.

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.
