Substance specification device, substance specification method, and substance specification program

A substance identification method comprising:

• setting an irradiation condition of excitation light;
• irradiating an object with the excitation light under the irradiation condition;
• measuring emission data for delayed fluorescence or phosphorescence of the object which occurs in response to the irradiation with the excitation light;
• and
• identifying a substance constituting the object based on the emission data and emission data for delayed fluorescence or phosphorescence which are measured when a plurality of substances are each irradiated with the excitation light under the irradiation condition.

A substance identification program for causing a computer in a substance identification device to function as:

• a setting unit that sets an irradiation condition of excitation light;
• an irradiation unit that irradiates an object with the excitation light under the irradiation condition;
• a measurement unit that measures emission data for delayed fluorescence or phosphorescence of the object which occurs in response to the irradiation with the excitation light;
• and
• an identification unit that identifies a substance constituting the object based on the emission data and emission data for delayed fluorescence or phosphorescence which are measured when a plurality of substances are each irradiated with the excitation light under the irradiation condition.

A substance identification device comprising:

• a setting unit that sets an irradiation condition of excitation light;
• an irradiation unit that irradiates an object with the excitation light under the irradiation condition;
• a measurement unit that measures emission data related to light emission of the object which occurs with a delay relative to irradiation with the excitation light;
• and
• an identification unit that identifies a substance constituting the object based on the emission data and emission data related to light emission which occurs with a delay when a plurality of substances are each irradiated with the excitation light under the irradiation condition.
