Abstract

The glass ceramics containing nanocrystalline lithium niobate in the 38B 2 O 3 30Nb 2 O 5 15Li 2 O 7KNO 3 5Sb 2 O 3 5Eu 2 O 3 ( glass system were prepared by the melt quench technique and controlling heat treatment. Samples were characterized by differential scanning calorimetry(DSC), X ray diffraction(XRD), scanning electron microscope(SEM) and fluorescence spectrophotometer and the factors affecting the crystallization of glass ceramics were analyzed. Scanning electron microscopy showed the fact that the LiNbO 3 nanocrystals dispersed in the glass matrix randomly. Fluorescence spectrum showed four emission peak, which located in the 578 nm ( 5 D 0 7 F 0 ), 592 n m 5 D 0 7 F 1 ), 61 5 nm ( 5 D 0 7 F 2 ) and 654 nm 5 D 0 7 F 3 The emission peak intensity of Eu 3+ in the glass ceramic sample were greater than that in the parent glass. The luminescence spectra of Eu3+-doped glass ceramics were recorded under 394 nm excitation and the luminescence intensity increase with the increasing of heat-treatment time. The optical transmittance reaches about 85% in visible light region. The Eu 3+ doped nanocrystalline LiNbO 3 glass ceramics are promising candidate materials as red light source due to the high luminescence intensity of Eu 3+ at 592 nm and 615 nm..
