Optical properties of γ-irradiated synthetic sapphire and yttria-stabilized zirconia spectroscopic windows
Source abstract
Abstract
Abstract Synthetic sapphire and yttria-stabilized zirconia single-crystals were irradiated by increasing doses of γ-radiation to study the changes of their optical properties. The optical transparency of α-Al 2 O 3 was nearly constant up to the γ-radiation dose of 150 kGy for the spectral range of 400–1000 nm, while yellowish-brown coloration of (Zr 0.89 Y 0.11 )O 1.94 appeared for irradiation above 1 kGy. However, after a short-term heating in the temperature of 210 o C stable discoloration of zirconia can be achieved.
