摘要：

Ni3-xCr2x/3(PO4)(2) (x=0 and 0.02) microcrystalline powders were obtained as single phases via a modified sol-gel Pechini-type in situ polymerizable complex method. The samples were characterized using scanning electron microscopy, X-ray diffraction, cathodoluminescence (CL), and thermoluminescence cm techniques. We found that Cr3+ doping modified the average particle and distribution. The mean particle size was 0.441 mu m for Ni-3(PO4)(2) and 0.267 mu m for Ni2.98C0.013(PO4)(2). The results also reveal that Cr3+ doping notably enhanced the CL and TL UV-blue emission. (C) 2013 Elsevier Ltd. All rights reserved.
