FLUORESCENCE INTENSITY INTENSIFYING CHIP

摘要

PROBLEM TO BE SOLVED: To provide an inexpensive fluorescence intensity intensifying chip having wide versatility and excellent corrosion resistance by using inexpensive SiO2 having wide versatility and excellent corrosion resistance as a dielectric. SOLUTION: In this fluorescence intensity intensifying chip capable of intensifying the intensity of fluorescence generated from a photo-excited phosphor by piling a metal, the dielectric and the phosphor on a glass substrate, SiO2 having the film thickness of 330 nm or less is used as the dielectric, and Ag or Al is used as the metal, respectively.
