The precursor glasses with the molar composition of 53P₂O₅-16BaO-9Na ₂O-7K₂O-14.25Gd₂O₃-0.75Eu₂O_3were prepared by high temperature m elting method,the melting temperature is 1400℃,and glass-ceramics are obtained by heat treatmen t.Their structural,morphology and luminescence properties are investigated by X-ray diffraction (XRD),scann ing electron microscopy (SEM) and luminescence spectrum.The results of XRD indicate that the glass ceramics containing Eu:GdPO_4can be obtained by heat treating the precursor glasses,an d the average crystallite sizes are 39nm and 55nm for glass ceramics prepared at 700℃ and 800℃ for 2h, respectively.The results of luminescence spectrum show that the emission and exc itation intensities of the glass ceramics are improved obviously,the relative intensiti es ratio of ⁷F₀-⁵L₆ transition to charge transfer band of O2－-Eu³⁺ decreases,the Stark splitting emission peaks are observed for glass ceramics,and relative intensities ratio of ⁵D 0-⁷F₂/⁵D₀-⁷F₁ decreases compared with that of precursor glass.All these demonstrate that the Eu³⁺ i ons are incorporated into GdPO_4nanocrystal phase.The emission and excitation intensities of glass ceramics increase with the heat treatment temperature increasing.
