Preparation and structural properties of Lu2O3:Eu3+ submicrometer spherical phosphors

Preparation and luminescence characterization of new carbonate (Y2(CO3)3·nH2O:Eu3+) phosphors via the hydrothermal route

“…Hence, it clearly reveals that the structural symmetry of Y 3+ was substituted by Eu 3+ is low in the lattice. The position of emission wavelength was reported to vary slightly with Eu 3+ coordination number [17]. Eu 3+ located at 6-coordination, 9-coordination and 12-coordination sites will generate emission at 611, 615 and 625 nm, respectively.…”

Specific features of the structure of ZnO nanocrystals grown in pores of Y2O3 spherical matrices

“…As a result, an alternative approach to ZnO formation was proposed in [16,17]: nanocrystals are grown in mesopores of monosize nano-and submicron Y 2 O 3 spheres [18][19][20][21][22] with the formation of Y 2 O 3 matrixZnO filler nanocomposites. The zinc oxide nanophase formation in a pore facilitates the slow removal of gaseous products of the zinc nitrate thermolysis reaction (O 2 and NO 2 ); thus, the conditions for retaining oxygen during the ZnO formation are formed.…”

Eu3+-doped CdMoO4 red phosphor synthesized through an aqueous solution route at room temperature

“…[1][2][3][4][5]. Among these rare-earth elements, trivalent europium (Eu 3+ ) with red luminescence is of technological importance and has been widely applied to phosphors owing to its high quantum efficiency, good stability and suitability for use in white light-emitting diodes [6][7][8]. Rare-earth oxide has been dominantly used as host material for Eu 3+ doping owing to its unprecedented red emitting phosphor with high luminescence quantum efficiency in fluorescence lamps and projection television tubes [7,8].…”
