Abstract

A spectroscopic measurement apparatusA comprises an integrating spherein which a sample S is located, a spectroscopic analyzerdispersing the light to be measured from the sample S and obtaining a wavelength spectrum, and a data analyzer. The analyzerincludes an object range setting section which sets a first object range corresponding to excitation light and a second object range corresponding to light emission from the sample S in a wavelength spectrum, and a sample information analyzing section which determines a luminescence quantum yield of the sample S, determines a measurement value Φof the luminescence quantum yield from results of a reference measurement and a sample measurement, and determines, by using factors β, γ regarding stray light in the reference measurement, an analysis value Φ of the luminescence quantum yield with the effect of stray light reduced by Φ=βΦ+γ. This realizes a spectroscopic measurement apparatus, a measurement method, and a measurement program which can reduce the effect of stray light generated in a spectrometer.
