Formation mechanism and morphology-dependent luminescence of NdF3 nanoplates with cavities

Abstract

NdF₃ is an excellent efficient material for infrared fluorescence and solid-state lasers. Herein, we describe the formation processes and a possible formation mechanism for single crystal NdF₃ nanoplates with cavities via a simple hydrothermal method. Enhanced infrared fluorescence and decreased upconversion emissions were observed from the NdF₃ nanoplates with cavities, which were attributed to the porous structure, and surface defects availed nonradioactive relaxation of the Nd³⁺. These single-crystalline NdF₃ nanoplates with cavities will provide new perspectives and opportunities in fascinating light phosphor powders and advanced devices.
