Is it possible to have two luminescence bands of the same peak position but with different intensities in single spectrum??

Hi! If it is possible to have two luminescence bands of the same peak position in a spectrum, what is the reason behind formation of two separate bands instead of one? This phenomenon is related...

Why use STOP solution in ELISA?

At the last step for data analysis, we always use a STOP solution to stop the TMB oxidized by HRP. Why do we have to stop the reaction? Couldn't we measure the color wavelength of...

What would cause Cell Titre Glo assay wells to luminesce less than the media only wells?

Hi all, I'm doing a bunch of Cell Titre Glo assays to assess the effects of several inhibitors on 2 cell lines. Problem is, for some of the wells they seem to be luminescing less than the...

How I can find the quantum efffcincy from the measured and calculated decay time when the measured decay time is greater than the calcualted decay ?

I am working on the luminescence properties of Nd3+ ions doped phosphate glasses for which I have to study the decay time. I measured the decay time experimentally and also calculated the decay...

How to avoid getting organic particles to charr(become black) during calcination?

I am trying to synthesize SrHfO3:Eu2+ nanoparticles. To reduce from Eu3+ to Eu2+, we calcinate it under Ar/H2 conditions but it ends giving a black coloured product. We need this for luminescence...
