Photoluminescence properties of forsterite (Mg2SiO4) nanobelts synthesized from Mg and SiO2 powders

Ternary oxide forsterite Mg2SiO4 single-crystalline nanobelts have been synthesized at high yields via SiO2 assistant-oxide through a VS process. The PL properties of the forsterite Mg2SiO4 nanobelts were observed. The emission peak at 625 nm is attributed to the 4T1 - 6A1 transition of the trace Mn2+ ions. The other emission peak at 400nm may be due to the defects.
