I know there are some poymers which will absorb light at one wavelength and then emit it at a lower wavelength but I don't know much beyond that. Can anyone point me to an article, paper or...

Most of the articles report PLQY values below %10 for systems radiates through up-conversion mechansim while down-conversion PLQY values reach up to 80-90 %. Is there a theoretical limit?

I would like to fixate some nanoparticles in a glass cuvette and excite them with UV (355nm and 266nm) laser light, studying their luminescent properties. I tried gelantine, but this is...

Sometimes before charge/discharge Li ion half cells do measure negative OCV open circuit voltage ( ~ -1.5 V). It's very rare but did came across some of the cells. Could you please share your...

Well a yellow laser should be around 575-580 nm. Concurrently, mixture of green and red photons are also looks yellow. So can we call it as a laser or it will be just a high-powered yellow flash...

I generated these RKO Cas9 stable cell line to knock out p53 using different sgRNA (one at a time). To do that, I need to induce the expression of Cas9 with Doxycyclin. I have been using 4ug/ml...
