Are there ways to calculate or simulate the luminescence spectrum?

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...

How can I find a Raman spectrum wavenumber corresponding to what compound?

I have several Raman spectra with very distinct peaks at certain wavenumbers, such as 277, 359, 466, 583, 623, 686, and 795cm-1. How can I identify them to what compound(s)? The RRUFF and others...

What are difference between laser diodes, simple light emitting diodes and power light emitting diodes when operated in the visible spectrum ?

I want to illuminate a scene (small space) using LED to capture photographs or videos of some tiny objects inside the space. But am not sure if I should use a Laser LED, or simple LED or power...

How to detect uv vis spectrum of nanoparticle under 300nm?

I try to make the indium nanoparticle and check the uv vis spectrum. I heard that In nanoparticle has surface plasmon resonance peak at 200~300nm. But most of solvent has absorption peak under...

Can you correct the wt%/at% of an incorrectly assigned peak in EDS?

For instance, I get a spectrum and the software incorrectly assigns a Si peak as W. If I don't catch it on the software and only have the report (which lists both wt% and at%), is there a way to...

Could we interpret the intensity of the peaks of the FTIR spectrum correlating to the concentration of some compound?

If we analyze the extract of two plants from the same species (for example) and there are very similarities between the two IR spectra except for the intensity of one peak at the same wavenumber....

Abubakar Abdussalam

@ Tyutrin, can elucidate further on what precisely you mean by "calculate" in your question? Are you referring to chemiluminescence, electro chemiluminescence or fluorescence? Your explanation would pave way to respond appropriately to your question.

Аlexander А. Tyutrin

Abubakar Abdussalam thank you for question! I want to know are there ways to obtain a theoretical curve of photoluminescence of color centers ?

Volkan Altunal

Hi Аlexander А. Tyutrin,

Different filters can be used in front of the PM tube during the experiment to obtain roughly information about the color centers of the experimentally obtained photoluminescence curve. Thus, you can easily draw the data against the wavelength.

I can say that this method is suitable for preliminary study. If you need a spectrum for further research, I suggest you do an x-ray luminescence analysis instead of simulating.
