| Abstract: | CaAl2B2O7: Eu was synthesized by solid reaction. The vibrational spectrum of theCaA12B2O7: Eu was investigated. It is showed that the vibration absorptions of the BO3 groupsare present in the 1400 ~ 600 cm- I region, and the bands peaking at 519 cm- 1 originates fromthe AlO6 vibration probably. The luminescent properties of Eu3 in CaA12B2O7 were investigated. It is found that the Eu3 in CaA12BZO7 occupies two different sites. Investigation on thephonon sideband of Eu3 indicates that BO3 groups are present in the surroundings of Eu3 . |
