Synthesis and upconversion luminescence of monodispersed, submicron-sized Er3+:Y2O3 spherical phosphors

“…Subsequent MPR processes populate the 4 S 3/2 / 2 H 11/2 and 4 F 9/2 levels. Bright green (centered at 563 nm) and red (centered at 660 nm) emissions are observed because of the radiative transitions (RTs) of 4 can be explained by the morphologies of the powders in Fig. 4.…”

“…Upconversion luminescent materials doped with trivalent rareearth (RE) ions have attracted much attention due to their broad practical and potential applications such as upconversion lasers, three-dimensional volumetric displays, fluorescent labels, fiber optic amplifiers and so on [1][2][3][4][5][6]. In particular, Er 3+ ion has been widely doped because Er 3+ ion has energy levels that closely match the wavelength of commercial available InGaAs laser diode (LD) [7,8].…”

DMF effect on the morphology and the luminescence properties of Y2O3:Eu3+ red phosphor prepared by spray pyrolysis

“…Eu-doped Y 2 O 3 is a promising red phosphor because of its chemical stability and high luminescent efficiency [9][10][11][12][13][14][15]. Until now, most of commercialized phosphor materials have been prepared by a solid-state reaction technique.…”

Nanophosphor Coatings: Technology and Applications, Opportunities and Challenges

“…It can be applied to any problem, which allows for probabilistic formulation. It was used for spherical and polyhedral particles, monosized ones and those possessing a size distribution, ordered and randomly distributed on the substrate (Konrad et al, 1999a;Soules and Klatt, 1988;Urabe, 1980). There are numerous reports on the Monte-Carlo modeling of properties of CRTs (Busselt and Raue, 1988), X-ray imaging systems (Badano, 2003;Liaparinos et al, 2006), and LEDs (Borbely and Johnson, 2005;Chang et al, 2005).…”

“…Along with the possibility to explicitly account for the size, shape, and arrangement of phosphor particles on the substrate, it allows further parameters (e.g. roughness of particle surface, Konrad et al, 1999a) to be added and can be combined with theoretical methods (e.g. Mie scattering theory, Soules and Klatt, 1988;Liaparinos et al, 2006).…”
