The measurements shown below highlight the advantages of using Nefer Ka's SERS substrates.
Ultra-low background signal
Raman signal taken on and off a Rhodamine 6G analyte show the inherent low background signal using Nefer Ka's SERS substrates.
Spatially uniform signal
Raman measurements at 3 different spots along the coffee ring of Rhodamine 6G display a uniform signal.
Broad bandwidth of operation
Excitation wavelengths can be λ = 532 nm, λ = 632 nm & λ = 785 nm.
Optimal excitation wavelengths at around λ = 632 nm.
