Mercury telluride (
) nanoparticulate thin films have
been prepared by an electrochemical route. Rutherford
back-scattering measurements reveal the change in 
to
ratio as a function of electrolysis current density. The
observation of quantum size effect in an inverted narrow band gap
material, , with average crystalline size 5.35
,
has been demonstrated through its transmission electron
microscopy, optical absorption, photoluminescence and Raman
scattering studies. Unique optical properties of
nanocrystals have been observed that are found to depend upon
the crystalline size and compositional ratio of to
in .
