The luminescence properties of AlN with manganese and rare earth activators under ultraviolet and cathode-ray excitation

The emission spectra of self-, Mn-, Eu- and Sm-activated AlN luminophores under ultraviolet and cathode ray excitation as well as the excitation spectra for Mn and self-activated phosphors are measured. Basic information about the kinetics, excitation density dependence and energy transfer mechanism is given. The possibility of the direct excitation mechanism of Eu centres is discussed.
