Y3Al5O12:Cr3+ ceramics were prepared by a new method of electron beam synthesis. Special features of this method are the fast speed of synthesis, high phase purity and stoichiometry. The samples were characterized by SEM and XRD methods. After the samples structure was confirmed, the optical measurements of the excitation/emission spectra and luminescence kinetics were performed in a wide temperature range. Characteristic excitation and emission spectral features of the 6-fold coordinated Cr3+ ions were detected and investigated; their presence is solid proof of successful doping of the prepared ceramics samples with the trivalent chromium ions. The developed technique of ceramics synthesis can be applied to other samples with different chemical compositions.
