Abstract
La3PO7∶Eu3+ nanocrystals were successfully prepared by combustion method.The structure and morphology of the prepared samples were obtained by X-ray diffraction,scanning of electron microscopy,high resolution transmission electron microscope,respectively.It was found that the average size of the particles was about 80 nm.In La3PO7∶Eu3+ samples,the major emission peak is derived from the 5D0→7F2 radiation transition and has a strong red emission and better color purity.The results of emission spectra,laser selective excitation spectra and time-resolved spectra indicate that symmetry of the local environment of Eu3+ is lower and Eu3+ ions occupy at least two types of site in the La3PO7 nanocrystal.
