Chakradhar, Sreekanth RP and Nagabhushana, BM and Chandrappa, GT and Ramesh, KP and Rao, JL (2003) Solution combustion derived Zn2SiO4 : Mn green phosphors - A photo luminescence study. In: DAE Solid State Physics Symposium, Dec 26 - 30, 2003., Gwalior,India.
Zn2SiO4 : Mn green phosphor have been synthesized in aqueous medium by combustion process . The microstructures of crystalline products was characterized by XRD, SEM, TG-DTA and fluorescence spectroscopies. The luminescence of Mn2+ ion in Zn2SiO4 shows a green emission peak around 517-520 nm form the synthesized phosphor particles under UV excitation (251 nm). The luminescence is assigned to a transition from the upper 4T1 \rightarrow 6A1 ground state. The mechanism involved in the generation of a green emission have been explained in detail. The effect of Mn content on luminescence have also been studied.
