Paper Title:
Mechanism Analysis of FTIR Absorption Characteristic of MgO Nano-Powder
  Abstract

Nano-MgO powders with different size form 30 to 100 nm are prepared and measured by XRD and IR. FTIR results show that nano-MgO powder has abnormal infrared absorption behaviors compared with that of micron scale; and there exist blue shifts of infrared absorption peaks with the decrease of the particles size. But when the average particle size of nano-MgO powder is down to less than 50 nm, there are red shifts of infrared absorption peaks. The aim of the paper is to analyze the mechanism of IR absorption characteristic of MgO Nano-powder by a single- dimensional chain vibration model.
