A series of luminescent ion exchanged zeolite are synthesized by introducing various ions into NaY zeolite. Monometal ion (Eu 3+ , Tb 3+ , Ce 3+ , Y 3+ , Zn 2+ , Cd 2+ , Cu 2+ ) exchanged zeolite, rare‐earth ion (Eu 3+ , Tb 3+ , Ce 3+ ) exchanged zeolite modified with Y 3+ and rare‐earth ion (Eu 3+ , Tb 3+ , Ce 3+ ) exchanged zeolite modified with Zn 2+ are discussed here. The resulting materials are characterized by Fourier transform infrared spectrum radiometer ( FTIR ), XRD , scanning electronic microscope ( SEM ), PLE , PL and luminescence lifetime measurements. The photoluminescence spectrum of NaY indicates that emission band of host matrix exhibits a blueshift of about 70 nm after monometal ion exchange process. The results show that transition metal ion exchanged zeolites possess a similar emission band due to dominant host luminescence. A variety of luminescence phenomenon of rare‐earth ion broadens the application of zeolite as a luminescent host. The Eu 3+ ion exchanged zeolite shows white light luminescence with a great application value and Ce 3+ exchanged zeolite steadily exhibits its characteristic luminescence in ultraviolet region no matter in monometal ion exchanged zeolite or bimetal ions exchanged zeolite.
