Effect of ZnS nanoparticles on the photoluminescence of Sm3+ ions in methanol

D Kakoti; N Rajkonwar; N Dehingia; A Boruah; Purabi Gogoi; Pankaj Dutta

ZnS nanoparticles co-doped with Sm3+ ions were prepared in methanol medium for fixed Sm3+ and varying ZnS concentrations. Enhancements in absorption as well as photoluminescence efficiency of the co-doped samples were observed. This enhanced efficiency is attributed to the effective increase in oscillator strengths of the Sm3+ transitions because of the addition of ZnS nanoparticles.

DoS Using SCLC Measurements in Hydrogenated Silicon Films

Himanshu S. Jha; Purabi Gogoi; Mukesh Singh; Pratima Agarwal

Density of defect states (DoS) play a significant role in controlling the optoelectronic properties and performance of semiconductor devices. Space charge limited current measurements is a simple method to estimate the approximate density of states near Fermi level in semiconducting thin films.
