Quantum dots (QDs) consisting of CdSe (core) with CdS (shell) were synthesized by an
organometallic precursors method. The average sizes of CdSe/CdS core-shell quantum dots …

Lead sulphide (PbS) is an important direct narrow gap semiconductor material with an
approximate energy band gap of 0.4 eV at 300K and a relatively large excitation Bohr radius …

Optical properties of ZnS thin films coated with organic dye extract on different Zn 2+
concentrations from ZnSO 4 are presented in this study. The effects of concentration and …

Photovoltaic (PV) is the cleanest and most direct and efficient mode of solar energy

The need to harness the abundant solar energy resources cannot be overemphasized. The
major problem is that despite the enormous quantum of energy available to mankind from …

Energy is the motive force behind the sustained technological development of any nation
and Nigeria is blessed with reasonably high quantities of various energy resources. These …

TiO 2–ZnO core–shell nanograss (NG) hetero-structure comprising of small nanobranches
with sharp edge multiple arms was synthesized via two-step synthesis techniques. Liquid …

Cu2S semiconductor is a good material for solar energy absorber due to its character of non-
toxic, low cost and ideal band gap of 1.2-2.5 eV [1]. Copper sulphide thin films are …

TiO 2–ZnO core shell nanograss (NG) hetero-structure was synthesized via two-step
