Photoluminescence and Magneto-optical Properties of Zn1−xMnxO
율다세프,강태원,Vasiliy O. Pelenovich,Uygun V. Valiev 한국물리학회 2009 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.55 No.3
Zn1−xMnxO thin films on quartz substrates with a low concentration of Mn (1%) were prepared by using ultrasonic spray pyrolysis. Photoluminescence, optical absorption, and magnetic circular dichroism (MCD) measurements were conducted in order to study the optical and the magnetic properties of Zn0.99Mn0.01O. The free exciton lines are dominant in the spectra of these samples, which indicates a high crystal quality for the films. Magneto-optical measurements show a significant MCD at the band edge of Zn0.99Mn0.01O at room temperature.
