Er2O3 Erbium Oxide Nanoparticles CAS 12061-16-4 For Lithium Battery Cathode Material

Er2O3 (Er2O3) is a pink powder rare earth oxide with excellent physical and chemical properties. It is slightly soluble in inorganic acid, insoluble in water, and transforms into hexagonal crystallization when heated to 1300℃, and does not melt. The optical properties of this material are particularly outstanding and can be used to manufacture high-quality optical devices such as lasers, fiber amplifiers and spectrometers.
In the optical field, the high optical quality of erbium oxide significantly improves the transmission efficiency of light, reduces the scattering and reflection of light, and thus improves the performance of the device. In addition, erbium oxide is often used to make infrared lasers with an output wavelength of 2.3 microns and a high energy density, which is widely used in cutting, welding and marking processes.
In addition to optical applications, erbium oxide can also be used as glass colorant, catalyst and mercury absorbent in fluorescent lamps, showing its wide application potential. The preparation method is simple, the cost is low, and it is easy to large-scale production, which provides strong support for scientific and technological progress in many fields.

Used

Used as additives for new energy lithium batteries and cathode material of lithium battery. The main uses of nanometer erbium oxide are as follows: 1. The optical emission of Er3+ at 1550nm is of special significance, because the wavelength is located at the lowest loss of optical fiber in optical fiber communication, and the optical loss is the lowest when signal light is used at 1550nm in optical fiber communication. In this way, if the appropriate concentration of nano erbium oxide is doped into the appropriate matrix, the amplifier can compensate the loss in the communication system according to the laser principle. Therefore, in the telecommunication network that needs to amplify the wavelength 1550nm optical signal, the nano erbium oxide fiber amplifier is an indispensable optical device. At present, the nano erbium oxide silica fiber amplifier has been realized Commercialization. It has been reported that in order to avoid useless absorption, the doping amount of nanometer erbium oxide in the optical fiber is tens to hundreds of ppm. The rapid development of optical fiber communication will open up a new application field of nanometer erbium oxide. 2. The laser crystal doped with nanometer erbium oxide and the 1730nm laser and 1550nm laser output are safe for human eyes, with good atmospheric transmission performance, strong penetrating ability to the battlefield, good confidentiality, not easy to be detected by the enemy, and large contrast to the military target. The portable laser rangefinder safe for human eyes in military affairs has been made. 3. Er3+ can be added into glass to make rare earth glass laser material, which is the solid laser material with the largest output pulse energy and the highest output power at present. 4. Er3+ can also be used as the activation ion of rare earth up conversion laser materials.
