摘要	Intense photoluminescence at room temperature was observed in amorphous cadmium aluminum silicate doped with europium prepared by the sol-gel method. The structure of the 3CdO-Al2O3-3SiO(2):Eu3+ system (CAS:EU3+) has been determined by transmission electron microscopy (TEM) and X-ray diffraction (XRD). The excitation and the emission spectra indicated that the red characteristic emission (611 nm) of CAS:Eu3+ under UV excitation due to D-5(0) -> F-7(2) electric dipole transition is the strongest. Both XRD data and the emission ratio of (D-5(0) -> F-7(2))/(D-5(0) -> F-7(1)) reveal that the EU3+ is in a site without inversion symmetry. The maximum photoluminescence intensity has been obtained for 25 mol% concentration of Eu3+ in CAS, and the intensity enhancement and lifetime increase of Eu3+ with increasing sintering temperature were observed due to the less OH-content in the samples.
