摘要：
Samples of GdBO3 doped with Ce3+ embedded in amorphous silica matrix were obtained by sal gel process and heat-treat at 1000 degrees C for 2 h in argon atmosphere. After elaboration, the samples were irradiated with gamma-rays using cobalt (Co-60) source in the dose range from 1 to 5 kGy. The irradiation effect of gamma-rays on structural and optical properties of the synthesized samples were investigated by X-ray diffraction (XRD), transmission electron microscopy (TEM), Fourier transforms infrared spectroscopy (FTIR) and photoluminescence spectroscopy. XRD and TEM-EDS results reveal that gamma-ray irradiation reduces the crystallite size from 55 nm to 30 nm. It is found from FUR study that the absorption bands intensity assigned to structural groups containing BO4 and BO3 units as well as the banding of Si-O-Si bond increases with gamma-ray dose up to 4 kGy. While photoluminescence measurements show that the emission bands attributed to the 5d -> 4F transition of Ce+3 ion intensity decreases, it is still significant even after irradiation to a dose of 5 kGy. From this results it is concluded that the gamma-ray irradiation up to a dose of 5 kGy improve the structural and morphological quality of the synthesized GdBO3/silica: Ce3+ without altering significantly its luminescence properties.
