Abstract: (3910 Views)
In this work, the nanoscale Y2O3 powder was prepared with Nd2O3 ion at 1, 1.5 and 2% mol by ball milling for 20 hours, the particle size decreased significantly to 92.3 nm. A transparent pure ceramic disc of pure Yttrium doped with neodymium, which is used as laser active medium in power lasers, was made by a plasma spark sintering with a heating rate of 100 °C/min at 1400 °C for 15 minutes at a pressure of 70 MPa.The sample of Nd:Y2O3 transparency ceramic disc was significantly increased at the wavelength of the lens. The highest transmittance of Nd:Y2O3 ceramic reached 83% at the wavelength of 5 μm for 2.5 mm thick,Which is very close to the value of the theory of yttria that has been dopped to neodymium.
