Surface-Enhanced Raman Scattering Studies of Au-Ag Bimetallic Nanoparticles with a Tunable Surface Plasmon Resonance Wavelength Synthesized by Picosecond Laser Irradiation Open

P. Babuji, Md Abu Taher, Mudasir H. Dar, D. Narayana Rao, P. Gopala Krishna , et al. · 2023

Here, we present a simple and green method of preparing Au-Ag bimetallic nanoparticles (NPs) with a tunable surface plasmon resonance (SPR) wavelength by using picosecond laser irradiation. Au-Ag alloy NPs have been produced by irradiating…

Study of spatial rings in TPPOH<sub>4</sub> doped in boric acid glass Open

A. Srinivasa Rao, Mudasir H. Dar, N. Venkatramaiah, R. Venkatesan, Alok Sharan · 2015

Single beam optical nonlinearity is studied in TPPOH4 doped in boric acid sandwiched films between two microscope glass slides at three different molar concentrations (4×10−4M, 1×10−4M, 5×10−5M). It shows absorption peak at 700nm with band…
