Congratulations to Soumya Mukherjee , Anjan NM, Saranya Prakasi Ramesh from Ultrafast THz Spectroscopy Group and IISER Kolkata Department of Physical Sciences and Prof. B. Karthikeyan (Bala Karthik), National Institute of Technology Tiruchirappalli for the recent work on CuS and CuS/Ag2S nanocomposites where we looked at hole and electron dynamics using non-degenerate pump-probe spectroscopy. This work is published online at ACS Applied Optical materials and the link is

A detailed nondegenerate ultrafast pump-probe transmission study of CuS nanoflakes and CuS/Ag2S nanocomposites with varying pump fluences is conducted in this work. The measured transient transmission data for CuS are found to originate from a strong photoinduced bleaching of intrinsic holes and a w...
