摘要： PROBLEM TO BE SOLVED: To precisely read the content of information, and to prevent the error or forgery of reading by allowing a light emission mark containing a single light emitting material which emits a light by an excitation light in an ultraviolet area and a near infrared area to emit a light by each excitation light, detecting a light emission, and reading information written in the emission mark. SOLUTION: An operation such as printing, coating, and attachment is performed by using a light emission ink or light emission sheet containing a single light emitting material which emits a light with an excitation light in an ultraviolet area and a near infrared area to a base material, and necessary information is added by a mark such as a bar code so that the light emitting carrier is obtained. The light emission is detected by radiating the light emission mark of the light emitting carrier with an excitation light in ultraviolet area. Then, light emission is detected by irradiating the same position with an excitation light in near infrared area. It is confirmed that each information detected by the two excitation lights is the same. Compounds indicated by the formula are desired as the light emission materials to be used. In the formula, each of R -R independently indicates hydrogen atom, etc.
