Theoretical Analysis of the FTIR Absorption Characteristic of Nano-Powder

Abstract:

The infrared absorption behaviors of nano-MgO with different sizes have been investigated based on XRD and IR data. The blue shifts of infrared absorption peaks with the decrease of the particles size have been analyzed by constructing one-dimensional vibration model. Adopting the quantum physics analyzed method, we provide the reasonable explanations for the red shifts of infrared absorption peaks as the average particle size of nano-MgO powder is down to less than 50 nm.
