Anomalous dips in reflection spectra of optical polymers deposited on plasmonic metals

Autor: Shorter Ayanna, Chowdhury Md Golam Rabbani, Rout Sangeeta, Noginov Mikhail A.

Publikováno v: Nanophotonics, Vol 12, Iss 3, Pp 631-636 (2023)

We have studied reflection spectra of dye-doped and undoped polymers deposited onto Ag and Au substrates and found anomalous dips in the UV spectral range. On top of Ag substrates, the λ ∼ 375 nm dips were observed in undoped PMMA, PVP, and PS pol

Emission kinetics of HITC laser dye on top of arrays of Ag nanowires

Autor: Rout Sangeeta, Peters Vanessa N., Pradhan Sangram K., Bonner Carl E., Noginov Mikhail A.

Publikováno v: Nanophotonics, Vol 10, Iss 16, Pp 4027-4033 (2021)

We have grown arrays of silver nanowires in pores of anodic alumina membranes (metamaterials with hyperbolic dispersion at λ ≥ 615 nm), spin coated them with the dye-doped polymer (HITC:PMMA), and studied the rates of radiative and nonradiative re

Effect of nanoscale dielectric environments on concentration quenching

Autor: Rout Sangeeta, Koutsares Samantha R., Courtwright Devon, Mills Ezekiel, Shorter Ayanna, Prayakarao Srujana, Bonner Carl E., Noginov Mikhail A.

Publikováno v: Nanophotonics, Vol 10, Iss 14, Pp 3659-3665 (2021)

We have studied the dependence of concentration quenching of luminescence (donor–acceptor energy transfer) on the thickness d of dye-doped polymeric films (HITC:PMMA) and found its strong inhibition at small values of d. This phenomenon is tentativ
