No rare earths used! Silver-containing zeolite phosphor that achieves the emission of primary colors.
"Gaia Photon" is a silver-containing zeolite phosphor that fluoresces under ultraviolet and violet light, using zeolite as the base material and introducing silver ions through a room temperature cation exchange method. By examining the Si-Al ratio of the base zeolite, particle size, silver ion content, and the composition of secondary and tertiary components, as well as temperature conditions, it demonstrates approximately 50% of the luminous intensity of existing red phosphors (CASN) and about 150% of yellow phosphors (YAG:Ce) when irradiated with 405nm violet light. 【Features】 ○ Rare earth-free phosphor ○ Achieves emission of primary colors ○ High safety for the human body ○ Established mass production technology for safe use ○ Patent No. 5438728, Patent No. 5781477 For more details, please contact us or download the catalog.
