Optical absorption of electrolytically colored single crystals of yttria-stabilized zirconia

Electroreduction of yttria-stabilized zirconia (YSZ) has been reported to produce a broad optical absorption peak at 480–500 nm. This result is at variance with the empirically predicted absorption for F and F′ centers, which should occur at 325 nm and 400 nm, respectively. We electroreduced YSZ sin...

Description
Summary:Electroreduction of yttria-stabilized zirconia (YSZ) has been reported to produce a broad optical absorption peak at 480–500 nm. This result is at variance with the empirically predicted absorption for F and F′ centers, which should occur at 325 nm and 400 nm, respectively. We electroreduced YSZ single crystals at electric fields and temperatures lower than those used by earlier workers, and observed a broad absorption peak at 360–380 nm, in agreement with theoretical predictions.
