Precipitation Synthesis and Color‐Tailorable Luminescence of α‐Zr(HPO₄)₂: RE³⁺(RE = Eu, Tb) Nanosheet Phosphors

Abstract

The rare earth (RE = Eu and Tb) ions-doped a-Zr(HPO 4 ) 2 (ZrP) nanosheet phosphors were synthesized by direct precipitation method, and their structures and photoluminescence properties were investigated. The results of X-ray diffraction and scanning electron microscopy indicated that the systems of ZrP:RE 3+ had similar nanosheet structure except with relatively larger interlayer spacing as compared with pure a-ZrP. nanosheet phosphors may be a potential color-tailorable candidate for fabricating optoelectronic devices such as electroluminescence panels.

“…Because of the invaluable and high technological applications of rare earth elements, the recovery and demand of rare earth elements is continuously growing . Additionally, their nonbiodegradable and bioaccumulation tendency along with the toxicity concerns further necessitate their recovery from contaminated water. − Xu et al, investigated the selective sorption of Nd and Dy ions from Co–Nd–Dy ternary system onto crystalline α-ZrP and amorphous ZrP (Am-ZrP) .…”

“…Subsequently, the excited energy ( 5 D 1 ) of Eu 3+ is transferred to the lower excited energy state of Eu 3+ ( 5 D 1 → 5 D 0 ) by non-radiative relaxation[33,34]. After the non-radiative relaxation, the Eu 3+ ions cascade from the energy state increase in red emission intensity[28].…”
