The system Al-2O-3-B-2O-3-Ce-2O-3, with Al/B ratio varying from 4.5 to 2 and Ce/(Al+B)=0.02, has been prepared at the temperature from 1 200 to 1 400℃. Relationship between luminescence and matrices in the system Al-2O-3-B-2O-3-Ce-2O-3 was investigated. It was found that some changes of the matrices occurred with Al/B ratio varying from 4.5 to 2. These results lead to a great change in luminescence properties, indicating variation of Ce-surroundings of crystal field. With the decrease of the ratio from 3 to 2, the excitation and emission peaks shift to shorter wavelengths. It was also found that a new type of rare earth luminescent materials was obtained with appropriate Al/B ratio.

It was found that some changes of the matrices occurred with Al / B ratio varying from 4.5 to 2. These results lead to a great change in luminescence properties, indicating variation of Ce-periphery of crystal field. With the decrease of the ratio from 3 to 2, the excitation and emission peaks shift to shorter wavelengths. It was also found that a new type of rare earth luminescent materials was obtained with the appropriate Al / B ratio.
