Abstract

Europium doped zinc silicate (Eu:Zn₂SiO₄) phosphors in the forms of nanoscale powder and film has been prepared by sol-gel method. XRD analysis indicated that the powders have willemite structure with a small amount of triclinic structure and the film has pure willemite structure. Photoluminescence measurement showed that strong red emission of Eu³⁺ ⁵D₀→⁷F₂ transition could be obtained under excitation at both 256 and 393 nm. Luminescence decay of the emission under 393 nm excitation can be fitted by a single exponential, yielding a decay time τ=1.43 ms; and the luminescence under 256 nm excitation shows double exponential decay with a slow decay time τ_s=2.13 ms and a fast decay time τ_f=2.05 ms.
