We report the results of a study of the growth of pores in n-CdSe single crystals using anodic etching techniques. Upon anodization in dark, a nonuniform distribution of pores was produced. However, anodic dissolution of the material under in situ UV illumination proves to result in uniform distribution of pores stretching perpendicularly to the initial surface of the specimen. The porous structures exhibit less luminescence than the bulk samples. These results pave the way for cost-effective manufacturing of CdSe-based semiconductor nanotemplates for nanofabrication.

    So far, excitonic luminescence in metal halide (MH) has extensively been studied by many workers, with the interest not only in physics of excitons but also in its possible application in optoelectronics. In the actual MHs, however, excitonic luminescence is so weak that it is beyond the scope...
