Indicators, absorption maxima color change

One basic requirement is an overlap of the emission of the UCNPs and the absorbance of the indicator probe that need not be fluorescent. Its absorbance has to change with the concentration of the anal3de of interest. A color change results in a stronger or weaker quenching (absorption) of the upconversion emission depending on the acmal maximum of absorbance of the indicator. [Pg.39]
