Abstract:
Vanadium doped ZnS quantum dots (QDs) were synthesized with the generic formula Zn1–x V x S (where x = 0, 0.05, 0.10 and 0.15). Polyvinylpyrrolidone capped QDs were prepared by chemical co-precipitation technique. The phase purity of the samples were confirmed by x-ray diffraction. Crystallite size of 1.7–2.2 nm was obtained from the Scherrer's formula. Optical absorption studies revealed a band gap varying from 3.9 to 4.1 eV. Photoluminescence studies revealed a strong blue shift due to the strong quantum confinement in the particles. Magnetic studies indicated a ferromagnetic ground state for the doped samples.

THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
