Abstract :
The feasibility of calibrating the power spectra of light-emitting diodes (LED´s) by direct substitution against a tungsten standard lamp is demonstrated. Because LED´s often emit in more than one band over a wide spectral range, spectral interval standards are proposed to characterize the quantum efficiency of the intended dominant recombination processes in GaP and GaAsP.
