Abstract:

A possible source of error in measuring luminescent decay times as a result of photomultiplier saturation is discussed. Photomultiplier saturation can occur by exceeding the maximum linear output current, which decreases with increased light pulse duration. For this reason it is necessary to calibrate the instrument response appropriate to the lifetime and light intensity being measured. Author
