“…05-0586), demonstrating that the CaCO 3 host is formed. 20 The XRD result of the G-CDs/SiO 2 composite reveals a broad diffraction peak in the standard diffraction peak range of the previously reported SiO 2 and CDs between 10° and 40°, which implies that CDs may be loaded within the SiO 2 host. 21,22 TEM and high-resolution TEM (HRTEM) are used to characterize the morphology of the B-CDs/CaCO 3 and G-CDs/SiO 2 composites to further confirm that CDs have been successfully loaded into the matrix.…”

“…The calculations of formation energy and occurrence probability both prove the occupying information for the multi-site phosphors. Especially when Eu 3+ is the activator, the Judd–Ofelt theory can be used to investigate symmetry, coordination environment and luminescence behavior [ 96 ]. Figure 12 c exhibits the PL emission spectra of a series of CaCO 3 :Eu 3+ samples.…”

The development of novel phosphor materials with excellent performance and modification of their photoluminescence to meet the higher requirements for applications are the essential research subjects for luminescent materials. Multi-site luminescent materials with crystallographic sites for the activator ions that broaden the tunable range of luminescent spectra and even enhance the luminescent performance have attracted significant attention in the pursuit of high-quality luminescence for white light-emitting diodes. Here, we summarize multi-site luminescence characteristics based on the different kinds of host and activator ions, introduce the identifications of multi-site activator ions via optical analysis, provide a structural analysis and theoretical calculation methods, and introduce the regulation strategies and advance applications of multi-site phosphors. The review reveals the relationship between crystal structure and luminescent properties and discusses future opportunities for multi-site phosphors. This will provide guidance for the design and development of luminescent materials or other materials science.
