The high-temperature (T = 1880◦C) Be-ions diffusion and electron irradiation influence on the AlN monocrystals optical properties were investigated. We demonstrated that Be diffusion into AlN leads to spectral properties change of the Raman scattering and infrared absorption. The analysis of the Ramanand infrared absorption spectra of the AlN crystals, containing Be impurity, proves that Be impurity is a getter for intrinsic impurities, which are responsible for AlN crystals yellow color manifestation and spectral lines broadening
