UV-induced defect formation in cubic ZrO2. Optical demonstration of Y, Yb and Er dopants interacting with photocarriers
Chemical Physics Letters(2020)
摘要
•UV-induced photocoloration of cubic zirconia monitored by DRS spectroscopy.•Doped c-ZrO2 (with Y, Yb, Er) synthesized and characterized by DRS, SEM and EDS.•Narrow f‒f absorption of Yb3+ & Er3+ used to show interactions with photocarriers.
