Time-resolved spectra of coumarin 30-rhodamine 6G dye mixture
R D Singh D Mohan A K Sharma N V Unnikrishnan
The effect of acceptor concentration on the energy transfer from Coumarin 30 (donor) to Rhodamine 6G (acceptor) has been studied. The nature of energy transfer reaction has been studied through lifetime measurements by recording the time-resolved fluorescence decay curves. The energy transfer parameters calculated were used to confirm the occurrence of energy transfer on the basis of the emission-reabsorption effect.

Pulsed laser induced absorption (one–four) dependence of electron mobility in CdI2 and ZnS crystals
R D Singh Arun Gaur A K Sharma
The photoconductivity and electron mobility of CdI2 and ZnS crystals have been studied using N2-laser, fundamental and frequency doubled Nd:YAG laser. Low values of the electron mobilities obtained in the present case have been attributed to laser-induced-absorption. It is low in one photon excitation and increases with the order of absorption.

New method for the evaluation of the RKR potential-integrals for diatomic molecules
Suresh Chandra A K Sharma Z H Khan
We present a new method for the evaluation of the RKR potential-integrals for diatomic molecules. This method is straightforward and fast, and the calculations can be performed to an accuracy better than any other method.
