Quantum Yield Calculator From Photoluminescence (PL) and UV-Vis Absorption

Quantum Yield From Photoluminescence (PL) spectra and UV-Vis Absorption Calculator Data of Standard/Reference Quantum Efficiency PL: Area Under Peak UV Absorption Refractive Index of Solvent Data of Sample PL: Area Under Peak UV Absorption Refractive Index of Solvent Results (Quantum Yield) % Theory Behind Calculations: The above calculator is based on following relation: QY-sample = (QY-std * PL-sample * Abs-std * RefrativeIndex-sample^2) / (PL-std * Abs-sample * RefrativeIndex-std^2) Note: UV-Vis absorption must be less than 0.1 (Intensity a.u.) to minimize the resorption of photons. --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
