Abstract |
: |
The research is aimed at introducing the low temperature and extremely simple method of preparing
ZnS:Te, within aqueous media. In order to accomplish this research objective, the research is intended
to perform analysis of the prepared nanoparticles by using different techniques. Some of the major
techniques include X-ray diffraction, optical transmission, photoluminescence (PL), and infrared and
Raman spectroscopies. In this research, ZnS(1-x)Te(x), with x = 0.0, 0.05 and 0.2 nanoparticles, was
synthesized, for the first time, in aqueous medium by colloidal method. The synthesized nanoparticles
were characterized by using XRD, EDX, and UV-Vis optical transmission, PL, thermogravimetric, and
FTIR and Raman spectroscopies. XRD analysis confirmed that the prepared nanoparticles had zinc
blende structure and that the size of nanoparticles ranged from 1.8 to 2.5 nm. Optical transmission
revealed energy gap of 4.05-3.36 eV and high transmission in the infrared region of the prepared
nanoparticles, doped with Te. PL and PL excitation showed formation of isoelectronic trapping states in
forbidden gap for the doped nanoparticles |
