Effects of precursors in the ethanol-based sol–gel synthesis of Zn2SiO4:Mn phosphor

Letter

Zn2SiO4:Mn is an efficient green-light-emitting phosphor for lamps, plasma display panels (PDP), electroluminescene (EL) devices, and liquid crystal display (LCD) backlights due to its high photoluminescent efficiency and chemical stability [1, 2, 3, 4, 5].

The authors reported simple sol–gel synthesis and green luminescence of nanocrystalline Zn2SiO4:Mn phosphor instead of the traditional high-temperature, solid-state reaction with a micron-sized phosphor [6]. The sol–gel process is a very flexible low-temperature process for synthesizing nanosized materials [7]. It allows one to easily obtain the desired composition as well as a high degree of uniformity. In the authors’ previous study, only zinc acetate and manganese chloride were used as zinc and manganese precursors, respectively [6].

The results of an ongoing study of the effects of the zinc and manganese precursors for the sol–gel route are reported herein. Ethanol was used as a solvent, as in the authors’ previous study....
