Paper Title:
Application of Raman Spectroscopy on Size Driven Phase Transition in Bismuth Titanate
  Abstract

Bismuth titanate nano-crystals were prepared successfully by sol-gel method and the critical particle size for phase transition was analyzed by Raman techniques. The results revealed the new Raman peaks at the wave number about 87, 227, 442, 467, 577 and 617cm-1 discerned gradually with increasing the particle size and abrupt increase in integrated intensity ratios of these modes, companied with strong decrease of half-widths happened at the particle size ranging from 18 to 33nm, which suggested an obvious size driven tetragonal-to-orthorhombic phase transition in Bismuth titanate nano-crystals.
