The Ideal

In consideration of the Sm3þ-centered characteristic orange-light as the ideal color-primary component toward a dichromatic white-light, herein, through the doping of the complex [Sm(acac)3(5-Br-2,20-bpy)] (2; Hacac ¼ acetylacetone; 5-Br-2,2′-bpy ¼ 5-Br-2,20-bipyridine) into the PVK (PVK ¼ poly(N-vinyl-carbazole)) host, the obtained PVK@2 film (10:1, wt/wt) exhibits the straightforward solid-state white-light (ΦPL ¼ 6.7%). Further using the PVK@2 film (10:1; wt/wt) as the emitting layer, its singlecomponent solution-processed WPLED gives the electroluminescent performance (LMax of 360.9 cd/m2, ηMax c of 1.08 cd/A) satisfactory enough for portable full-color flat displays

Based on the doping of the binary tris-pyrazolate-Sm3þ complex [Sm(tba-PMP)3(5-Br-2,20-bpy)] (1; 5-Br-2,2′bpy ¼ 5-bromo2,20-bipyridine and Htba-PMP ¼ 1-phenyl-3-methyl-4-(tert-butylacetyl)-5-pyrazolone)) with an efficient orange-light into the PVK (poly(N-vinylcarbazole) host, the obtained PVK@1 films exhibit the dichromatic color-tuning (white-light to purplish-pink and to pink) characters strictly relative to the Sm3þdoping content and the λex wavelength. Further using the PVK@1 film (10:1; wt/wt) with the straightforward white-light (ΦPL ¼ 5.8%) as the emitting layer, its single-component solution-processed WPLED gives the electroluminescent performance (LMax of 157 cd/m2, ηMax c of 0.65 cd/A and the white-light-emitting stability) satisfactory enough for portable full-color flat displays.

A new kind of Ca4Si2O7F2:Ce3+, Tb3+, Sm3+ oxyfluoride phosphor micron belt mat was obatained by simply electrospinning process and subsequent heat treatment. XRD result shows that a pure Ca4Si2O7F2 phase can be obtained at low temperature of around 900 °C. The micron belt precursor has a smooth surface and uniform morphology, and the width and thickness of the belt is about 2 μm and 200 nm. The morphology of micron belt is well retained after heat treatment, forming a plat phosphor mat consisting of uniform micron belt network. Ca4Si2O7F2:Ce3+, Ca4Si2O7F2:Tb3+, and Ca4Si2O7F2:Sm3+ exhibit the characteristic emissions of Ce3+ (4f7→4f65d1, blue), Tb3+ (4f8→4f75d, green), and Sm3+ (4f6→4f65d, red) under the excitation of near-UV light, respectively. By adjusting the doping concentration of Ce3+, Tb3+, Sm3+ ions a white emission in a single phase was obtained under the excitation of 360 nm. We have demonstrated that Ca4Si2O7F2:Ce3+, Tb3+, Sm3+ phosphor mat can be a promising candidate for a color-tunable phosphor mat applied in a near-UV White light emitting diodes.
