In this paper, we have investigated photoluminescence (PL) of Sm3+ doped ZrO2 coatings formed by plasma electrolytic oxidation (PEO) of zirconium in electrolyte containing Sm2O3 powder. Obtained PL emission spectra feature two distinct regions. The first region is related to ZrO2 PL band with maximum positioned at about 490 nm, while the second region in the orange-red part of the spectrum shows four sharp emission bands which are related to f-f transitions of Sm3+ from excited level 40312 to the lover levels H-6(J) (J=5/2, 7/2, 9/2, and 11/2). Increase of PL with time is related to increase of oxygen vacancy defects and the content of Sm3+ in the coatings formed during the process. (C) 2015 Elsevier B.V. All rights reserved.
