“…The diffusion process to prepare powder samples is very facile, which has been extensively applied to the preparation of various nano-sized sulfide materials. The SrS: 4 Ce 3+ nanophosphors resulted from SSDM have optical properties similar to phosphor resulted from the former method but the rate of diffusion of impurities is much higher than that synthesized by solid state reaction or sol-gel method [17].…”

“…This method of synthesis often provides the control over particle size and morphology as well. [43] The precursors are made to react through diffusion process, by ensuring that the temperature is just enough to have adequate diffusion and helps to complete the reaction without melting the constituents. [44] However, aluminates cannot be prepared by the solid-state diffusion method at temperatures up to 1400 C. in the field of material science.…”

The article briefly reports the fundamental scientific principles and landmarks in the field of luminescence and further enlightens the importance of persistent phosphor that is now widely used in luminous paints. Its main focus is on phosphorescence that makes use of lanthanides that have gained paramount importance in various crosssections of luminescent applications. Both inorganic and organic afterglow materials, synthesis and characterization along with skilled researchers' essential updates on emerging trends and efforts are elucidated at length. It exclusively reviews the red/green/blue organic/inorganic/hybrid phosphorescent materials and the latest advances in the development of novel long afterglow materials that can accelerate the green technology in the world of luminescence.

Nanocrystalline SrS phosphors doped with Ce ions at different concentrations (0.5, 1, 1.5 and 2 mol%) are synthesized via the solid-state diffusion method (SSDM), which is suitable for the large-scale production of phosphors in industrial applications. The as-prepared samples are characterized using an X-ray diffraction (XRD) technique, field emission scanning electron microscopy (FESEM), high-resolution transmission electron microscopy (HRTEM) and energy-dispersive X-ray (EDX) analysis. The optical properties of these phosphors are analyzed using reflectance spectra, photoluminescence spectra and afterglow decay curves. The cubic structure of the SrS phosphor is confirmed by XRD analysis and the crystallite size calculated by Scherer's formula using XRD data shows the nanocrystalline nature of the phosphors. No phase change is observed with increasing concentrations of Ce ions. The surface morphology of the prepared phosphors is determined by FESEM, which shows a sphere-like structure and good connectivity of the grains. The authenticity of the formation of nanocrystalline phosphors is examined by HRTEM analysis. Elemental compositional information for the prepared phosphors is gathered by EDX analysis. Photoluminescence studies reveal that the emission spectra of the prepared phosphor shows broad band emission centered at 458 and 550 nm due to the transition of electrons from the 5d → 4f energy levels. The afterglow decay characteristics of different as-synthesized SrS:Ce nanophosphors are conceptually described. Copyright © 2016 John Wiley & Sons, Ltd.
