|Title:||In Situ Synchrotron Radiation Small-angle X-ray Scattering Study Of The Kinetics Of Growth Of Cdte Nanocrystals In Borosilicate Glass|
|Abstract:||A number of isolator-semiconductor nanocrystal composites exhibit quantum confinement effects and nonlinear optical properties. In this work, the formation and growth of CdTe and CdTe0.9S0.1 nanocrystals immersed in a borosilicate glass host matrix were studied by small-angle x-ray scattering using synchrotron radiation during in situ annealing in the 560-580°C temperature range. The values of the average radii of the CdTe nanocrystals determined by using Guinier plots for different annealing times (20-30 Å) agree with those obtained from optical absorption spectroscopy measurements. The nanocrystal size distribution depends on the thermal history and composition of the samples. The existence of other structural heterogeneities having an average size of several hundred ångstroms was detected. © 1995 American Institute of Physics.|
