摘要：

We prepared a series of Li2O-CaO-Al2O3-SiO2/P2O5 glass ceramics doped with Mn2+ and Mn2+/Tm3+ ions by traditional high-temperature melting method and thermal annealing technology. The XRD pattern, TEM image, excitation and emission spectra of the samples were studied. The luminescent characteristics of the samples had been discussed in detail. The luminescent color of Mn2+-doped samples can vary from green to red by adjusting the ratio of SiO2 to P2O5. Under 360 nm excitation, the Mn2+/Tm3+-codoped sample can generate white light, whose CIE coordinate is (X = 0.328, Y = 0.314). The value is very close to the standard equal energy white-light illumination (X = 0.333, Y = 0.333). This study is helpful for exploring novel luminescent materials for white light-emitting diodes.
