Abstract
A confocal scanning laser microscope operating at 514 and 488 nm has been used to obtain two-dimensional (2-D) images of the mercuric bromide (HgBr2) crystal surface by photoluminescence, reflection, and transmission phenomena. Our measurements indicate that regions showing a strong photoluminescence may appear on the surface. By processing the 2-D images. we obtained the three-dimensional images, which offer a better possibility for the investigation. The analysis of spectral lines may be correlated with the presence of the Hg impurities.
