Within the last two decades, extensive research has been
devoted to study the fabrication and characterization of
chalcogenide compounds in the form of thin films [1].
Among these compounds, cadmium selenide is one of the
group II-VI semiconductors considered as a promising
material for the development of many interesting
applications such as nanosensors, biomedical imaging
device, photoelectrochemical, solar cells, optoelectronic
devices, electron-beam pumped lasers, light emitting
diodes, electroluminescent devices, etc [2-5]. CdSe is an
n-type semiconductor material [6] with a direct band gap
of 1.74 eV and a dielectric constant of 10.2 at 300 K. It
has high efficiency of radioactive recombination, high
absorption coefficient, high photosensitivity, and direct
band gap corresponding to a wide spectrum of
wavelengths from ultraviolet to infrared regions [7, 8] and
quantum size effects [9].
