  Amorphous silicon oxycarbide (a-SiCxOy) single doped with Yb3+ and co-doped with the couple Tb3+ - Yb3+ thin films were grown on crystalline silicon substrates by rf magnetron sputtering. The elemental composition in at. % is determined by energy dispersive spectroscopy and fourier transform infrared ...  Read More

Akanksha Prakash; Shailesh Narain Sharma

Volume 1, Issue 2 , 2016, , Pages 171-175


  Indium Phosphide quantum dots (InP QDs) having various applications can be used for both LEDs and photovoltaics owing to its highly luminescent properties and energy harvesting potential respectively. In our work we have synthesized InP QDs using hot injection technique. Further post synthesis treatment ...  Read More
