Abstract

BiOCl:Eu³⁺ ultrathin nanosheets were synthesized through a facile solvothermal method with the assistance of polyvinyl pyrrolidone. The ultrathin nanosheets showed a size ranging from 50-100 nm and a height of 2.9 nm, which is about four [Cl-Bi-O-Bi-Cl] layers. In addition, the luminescence properties and mechanism were investigated in detail, and compared with that of the nanoplate. It was found that the luminescence intensity for the BiOCl:Eu³⁺ ultrathin nanosheet was 6 times stronger than that of the nanoplate. Importantly, the oxygen vacancies act as a luminescence centers, and there was effective energy transfer from BiOCl ultrathin nanosheets to Eu³⁺ ions. In BiOCl:Eu³⁺ ultrathin nanosheets, white-light emission was observed under near-ultraviolet (NUV) excitation. These BiOCl:Eu³⁺ ultrathin nanosheets exhibit great potential as color-emitting phosphors for white light-emitting diode applications.
