Characterization of metal iodide quantum dots
Abstract
Different synthetic procedures for preparation of the nanometer scale metal iodide particles in liquid solutions and their incorporation in silicate glasses have been developed. Optical properties of small metal iodide particles that exhibit quantization effect has been examined. These particles are called quantum dots. Injection of electrons into semiconductor quantum dots colloids was studied by the pulse radiolysis technique. Excess electrons trapped on the surface lead to a blue-shift in the absorption edge of colloids. The change of crystal structure during the early stages of particle growth was followed by transmission electron diffraction and X-ray diffraction analysis.
