Abstract
The reaction between thin films of CdSe and aqueous HgCl2 was studied using electron diffraction (ED) powder X-ray diffraction (XRD), and X- ray photoelectron spectroscopy (XPS). It was found that alpha-Hg3Se2Cl 2 is formed in the CdSe film following its reaction with 0.01 M HgCl2 for a period of 5 minutes. Upon completion of the reaction of CdSe pow der with 0.01 M HgCl2, Hg2Cl2 is present in addition to alpha-Hg3Se2Cl 2 in a molar ratio of 1:3.1. The effect of air annealing on CdSe powde r was also studied. Heating in air to 450 degrees C for 1 hour resulte d in an XRD pattern corresponding to the hexagonal form CdSe.
