Review on Luminescence Spectroscopic Studies on Dy<sup>3+</sup> Doped Nano Phosphors

Abstract

In order to assess the luminescence spectroscopy experiments on Dy3+ doped nano phosphorus and metal oxides, this work includes a comprehensive literature analysis of final-results and discussion of prior research. In this review work, we take a look at what’s already been written about Dy3+ doped nano phosphorus and metal oxides. The collected sample was analysed by means of Powder X-ray Diffraction (PXRD), Fourier Transform Infrared Spectroscopy (FTIR), Optical Absorption (AOD), and Photoluminescence (PL). In metal oxides, Characterization techniques gives information about quality and composition of the samples, they exhibit unique PL spectra depending on impurities, crystal defects and mineral associations. These samples may be used in mining companies to assess the economic viability. Compared to an undoped phosphorus PL spectrum, a Dy3+ doped Nano phosphorus PL spectrum shows a blue emission at 441 nm (2.81 eV). Flux was used in a solid-state reaction to create a phosphor that emits white light and contains Dy3+ ions. Analysis of the manufactured sample was performed using Powder X-ray Diffraction (PXRD), Optical Absorption (AOP), Photoluminescence (PL), and Fourier Transform Infrared Spectroscopy (FT-IR). Intense crystal fields and Zeeman interactions can affect Dy3+ ions, as evidenced by their abundant resonance signals in EPR spectra.
