Abstract: A method for determining a variable of a sample is provided. At least one sensor substance is brought into contact with the sample and excited to luminesce by means of an electromagnetic excitation signal. The sensor substance is such that a relaxation time of its luminescence behavior depends on the variable of the sample to be determined. The electromagnetic excitation signal has a defined time-dependence, it is, for example, a frequency-modulated signal or a pulse sequence, in which distances between pulses are varied over the duration of the excitation signal. The time dependence of the luminescence response of the sensor substance is detected and an output signal is generated therefrom by integrating over specified time-intervals. An instant of time, relative to the time-dependence of the excitation signal, is determined, at which a step occurs in the time-dependence of the output signal. The value of the variable is determined from said instant of time.
