A white light emitting glass-ceramic. The chemical formula of the glass-ceramic is aSiO2.bAl2O3.cNaF.dCeF3.nDyF3.mAg, wherein a, b, c, d, n and m are, by mol part, 25-50, 15-30, 10-30, 10-25, 0.01-1 and 0.01-1, respectively, and a+b+c+d-100. A method for producing said glass-ceramic is also provided. Silver ion is doped in the glass-ceramic in the form of silver particles by means of sintering and reduction annealing treatment, and thus the luminescence properties of rare earth ion is improved.
