Trying to make a transparent contact above colloidal nanoparticles which illuminate light around 1500 nm. So I need low absorption at this wavelength. But in the literature always absorption spectra is given for visible range.
you can use Polypyrrole. PEDOT, PSS - conducting polymer.
I tried unsuccessfully to find any articles, where the Purcell enhancement of (Ge QD/Si-resonator) system would be shown from time-resolved experiments. Or any time-resolved measurements where Ge...

I'm researching light sources and their UV emissions. I'm curious if a 50W, 7500K conventional LED lamp emits any UV light. I found that a 200W tungsten lamp can emit up to 1.5 mW/cm² at 350 nm....
