Paper Title:
Measure of the Optical Properties of Semiconductor Pb3O4 Nano-Crystalline of Using Photo-Acoustic Technology
  Abstract

The application of new single-beam normalized photo-acoustic spectroscopy in semiconductor Pb3O4 nano-crystals photo-acoustic spectroscopy was carried out. The measured spectra of semiconductor Pb3O4 nano-crystals absorption coefficient of 0.95, and then measured the semiconductor Pb3O4 nano-crystals powders band gap is 2.3 . The TEM image shows the semiconductor Pb3O4 nano-crystals are round granular structure, while the XRD spectrum indicates that the semiconductor Pb3O4 nano-crystals are tetragonal. The grain size measured to be about 30nm, and the average particle size after the reunion is 100nm. Compared with the micron crystal, the optical properties of semiconductor nano-crystals and nano-particle size are closely related. By changing the size of semiconductor nano-crystals, doped to change shape and optical, electrical properties of the goal. Because the defense and photoconductive materials with very special properties, they were widely used in many areas of modern technology, especially in delay bombings and stealth coating.
