摘要：The BaB2O4:Eu3+ nano/microphosphors with sphere-, rod-, and granular-like morphologies were successfully obtained by a two-step method using Ba-B-O:Eu3+ as the precursor. The structure, morphology and photoluminescent properties of the products were characterized by Fourier transfer infrared spectroscopy (FT-IR), X-ray diffraction (XRD), thermogravimetry-differential thermal analysis (TG-DTA), scanning electron microscopy (SEM) and photoluminescence (PL). The formation mechanisms of Ba-B-O:Eu3+ and BaB2O4:Eu3+ were proposed. The results show that the BaB2O4:Eu3+ could retain the original morphologies of their respective precursors largely. The BaB2O4:Eu3+ prepared by this two-step method exhibited better morphology, smaller particle size and better crystallinity than when prepared by a solid-state method. The granular-like BaB2O4:Eu3+ red phosphor prepared by this two-step method exhibited stronger PL intensity and better red color purity than when prepared by a solid-state method. ? 2019 John Wiley & Sons, Ltd.
