Description
Near-infrared (NIR) luminescent materials play a vital role in photonic, optoelectronic, and biological applications. In this work, the ErTaO4 host was synthesized by a solid-state chemical reaction at 1200 °C for 4 h. X-ray diffraction (XRD) was used to confirm that the sample crystallized into a single phase, without impurities. Scanning electron microscopy (SEM) was used to confirm the morphology, which consists of irregular particles, and energy dispersive spectroscopy (EDS) confirmed the presence of Nd, Ta, Er, and O. The optical energy band gap of the material was determined from the Tauc plot. The photoluminescence (PL) was also employed to probe the photonic response of the material. The presence of electron trapping centres was confirmed using thermoluminescence (TL) spectroscopy. The depths of the electron trapping centres and kinetic orders were approximated using different methods. The study suggests that ErTaO4 have potential applications in luminescent inorganic materials for solid-state laser and dosimetry applications.
