Abstract

See full text

A spectral luminescence standard has bismuth in a light-transmissive inorganic matrix material and emits light in the near infrared region upon irradiation with excitation light. The bismuth acts as a luminescence emitter in the near infrared region. A method includes manufacturing such a spectral luminescence standard and a calibration medium which has the spectral luminescence standard in or on a carrier material.
