Abstract
Fabrication by sol-gel and study of the physical properties of Mn2+ doped Zn2SiO4 (Zn-SO-Mn) materials phosphors (heat-treated at 1500 degrees C) were reported. The morphology, microstructure and size of the particles were resolved by the XRD and TEM techniques. Moreover, PL measurements of the samples phosphors demonstrate a good emission at 576 nm (yellow: T-4(1)-(6)A(1)). The decay kinetics of the emission (yellow: T-4(1)-(6)A(1)) was analyzed (fitting: a single exponential function). After the adjustment, the Zn-SO-Mn samples exhibited that the lifetime is around 13.09 ms. These lifetime are considered as promising values compared to those obtained until now. In fact, these results provide a simple means of obtaining the phosphors have excellent yellow luminescence which is very interesting for several technological applications.
