“…Meanwhile, CO(NH 2 ) 2 produced a reducing atmosphere to convert Eu 3+ to Eu 2+ . Coprecipitation of metal nitrates with (NH 4 ) 2 CO 3 followed by annealing led to the production of Sr 409,410 and Sr 8 CaSc(PO 4 ) 7 :Eu 2+ by thermal treatment in a reducing atmosphere CO at high temperatures. 411 Another notable example is Sr 2 Si 5 N 8 phosphors doped with Eu 2+ used in solidstate lighting.…”

Impurity doping is a promising method to impart new properties to various materials. Due to their unique optical, magnetic, and electrical properties, rare-earth ions have been extensively explored as active dopants in inorganic crystal lattices since the 18th century. Rare-earth doping can alter the crystallographic phase, morphology, and size, leading to tunable optical responses of doped nanomaterials. Moreover, rare-earth doping can control the ultimate electronic and catalytic performance of doped nanomaterials in a tunable and scalable manner, enabling significant improvements in energy harvesting and conversion. A better understanding of the critical role of rare-earth doping is a prerequisite for the development of an extensive repertoire of functional nanomaterials for practical applications. In this review, we highlight recent advances in rare-earth doping in inorganic nanomaterials and the associated applications in many fields. This review covers the key criteria for rare-earth doping, including basic electronic structures, lattice environments, and doping strategies, as well as fundamental design principles that enhance the electrical, optical, catalytic, and magnetic properties of the material. We also discuss future research directions and challenges in controlling rare-earth doping for new applications.

“…21 The fullwidth at half maximum (FWHM) of this band is 49 nm, which is slightly narrower than the FWHM of BaMgAl 10 O 17 :Eu 2+ . 22 It is generally accepted that the luminescence properties of Eu 2+activated phosphors are easily affected by the crystal structure, especially the coordination environment of Eu 2+ ions. As can be seen from the inset in Fig.…”

“…At present, BaMgAl10O17:Eu 2+ (BAM: Eu 2+ ) is the most commercially used blue phosphor, which has a blue emission peaking at 452 nm with the FWHM of 55 nm [7]. Regretfully, the absorption of this phosphor in near-UV spectral region is not so ideal [8]. So, it is highly desirable to design and prepare novel blue phosphors effectively pumped by near-UV light.…”

Novel blue-emitting KBaGdSi2O7:Eu2+ phosphors were designed and synthesized through solid-state reaction method. The structural properties, concentration and temperature-dependent luminescence behaviors of this phosphors were investigated in detail in this paper. Studies revealed that KBaGdSi2O7:Eu2+ phosphors have an intense absorption in the broad wavelength ranging from 250 nm to 400 nm that is suitable for the commercial near-UV LED, and give out intense blue light peaked at 475 nm with a full-width half-maximum (FWHM) of 75 nm. The crystallographic information of KBaGdSi2O7 phase is revealed from XRD pattern by Rietveld refinement. Band gap is derived to be 3.93 eV through diffuse reflection spectra (DRS) through Kubelka Munk function. The concentration quenching mechanism is identified as the dipole-dipole interaction. Moreover, the thermal quenching experiment was also conducted and the activation energy is calculated as 0.3069 eV, which indicates this novel KBaGdSi2O7:Eu2+ phosphor has good thermal stability. These properties exhibit its potential commercial application for near-UV white-light LEDs (w-LEDs).
