Synthesis, structural characterization and optical study of Dy3+-doped langbeinite salts
چکیده انگلیسی
Several spectroscopic measurements on the synthesized samples were carried out: Fourier transform infrared spectroscopy showed the different vibration modes of sulfate group, the ultraviolet-visible-near infrared absorption spectroscopy revealed Dy3+ transitions from the ground state 6H15/2 to different excited levels and the emission spectra in the visible region revealed four emission bands originated from the 4F9/2 level to the 6H15/2, 6H13/2,6H11/2 and 6H9/2+6F11/2 levels of Dy3+ ions. Moreover, the temperature dependence lifetime of this emitting level can be explained in terms of the thermalization effect.
