DOI: 10.1016/j.molliq.2018.07.005
Abstract: Abstract The present work deals with experimental determination of steady state fluorescence anisotropies, fluorescence lifetimes and consequentially the rotational reorientation times of three large, nonpolar laser dyes that are modelled as prolate ellipsoids. Steady state… read more here.

DOI: 10.1088/1555-6611/aa555c
Abstract: We fabricated polyvinyl alcohol (PVA) nanofibers doped with Rhodamine 6G laser dyes via an electrospinning technique, which were then excited by a pulsed laser for laser emission. The laser was observed at a low threshold… read more here.
