Photoluminescence studies of cobalt (II) doped zinc silicate nanophosphors prepared via sol-gel method

In this study, cobalt(II) doped zinc silicate nanophosphors were prepared via a sol-gel route which the solution mixed, stirred and dried in the oven at 100 °C around 6–8 h then undergone different heat treatment (600, 700, 800, 900, and 1000 °C). The nanophosphors powder sample was characterized us...
