Abstract

The solid-state reaction method was used to prepare Ce³⁺/Eu³⁺ codoped KZnPO₄ phosphors for white light-emitting diodes (W-LEDs). The phase formation of Ce³⁺/Eu³⁺ codoped KZnPO₄ was verified by X-ray powder diffraction (XRD) analysis. Under excitation at around 395 nm, red emission corresponding to the ⁵D₀ → ⁷F₂ transition was observed from Ce³⁺/Eu³⁺ codoped KZnPO₄ phosphors. The codoped Ce³⁺ in KZnPO₄:Eu³⁺,Ce³⁺ affects the microstructural symmetry because of different ionic sizes, leading to the different emission properties of KZnPO₄:Eu³⁺. The codoping method may be efficient for adjusting the luminous characteristics of phosphors.
