- Abstract
Ca2ZrSi4O12:R (CZSO:R) (R = Eu3+, Bi3+, and Eu3+/Bi3+) phosphors are successfully synthesized in air through high-temperature solid-state method. Host CZSO and CZSO:Bi3+ phosphor with excitation at 300 nm emit blue light. CZSO:Eu3+ phosphor with changing Eu3+ content shows tunable emission from white to red light under excitation at 300 nm and only emits red light under excitation at 395 nm. CZSO:10%Eu3+, Bi3+ phosphor shows tunable emission from blue to red light under excitation at 300 nm, and only emits red light with excitation at 395 nm when Bi3+ ion concentration is changed. Luminescence properties of CZSO:Eu3+ phosphor may be improved by co-doping Bi3+ ion. The luminous mechanism of CZSO:Eu3+, Bi3+ phosphor is explained by the energy level diagrams of Bi3+ and Eu3+ ions.
