Quenching Concentration Solution

Follow our step by step solution on how to calculate Quenching Concentration?

FIRST Step Consider the formula

[Q1] = \frac{(\frac{Io}{I F}) - 1}{K SV}

Next Step Substitute values of Variables

∴

[Q1] = \frac{(\frac{500W/m²}{240W/m²}) - 1}{0.005}

Next Step Prepare to Evaluate

∴

[Q1] = \frac{(\frac{500}{240}) - 1}{0.005}

Next Step Evaluate

∴

[Q1] = 216.666666666667

LAST Step Rounding Answer

∴

[Q1] = 216.6667

How to Evaluate Quenching Concentration?

Quenching Concentration evaluator uses Quencher Concentration = ((Initial Intensity/Fluorosence Intensity)-1)/Stern Volmner Constant to evaluate the Quencher Concentration, The Quenching Concentration formula is defined as the concentration of an activator which is higher than an appropriate value (typically several mol%) for which the emission intensity of the phosphor mostly will be decreased. Quencher Concentration is denoted by [Q1] symbol.

How to evaluate Quenching Concentration using this online evaluator? To use this online evaluator for Quenching Concentration, enter Initial Intensity (Io), Fluorosence Intensity (I_F) & Stern Volmner Constant (K_SV) and hit the calculate button.

FAQs on Quenching Concentration

What is the formula to find Quenching Concentration?
