Theory Behind Calculations:

The above calculator is based on following relation:
QY-sample = (QY-std * Abs-std * PL-sample * RefrativeIndex-sample^2) / (Abs-sample * PL-std * RefrativeIndex-std^2)

Note: UV-Vis absorption must be less than 0.1 (Intensity a.u.) to minimize the resorption of photons.

2 Question, Ask New
KANIKA KHURANA says:

What reference was used for metallic nanoparticles deposited on glass thin films, FOR FINDING QUANTUM YIELD?

Bintu Kumar says:

Actually, what was found by me for calculating quantum yield, the absorbance of the standard was found 0.1 with the concentration of 10mm, but we did with our compound that time was found less than 0.01. So, queries regarding to that which concentration is good for calculation like 10mm or 10um because that time the absorbance was 0.35 at 10 um, other is can we take absorbance in nm, not an intensity height. I curious about your immediate response
