Single-phased, high-color-rendering index (CRI) white-light phosphors are emerging as potential phosphor-converted white-light-emitting diodes (WLEDs) and an alternative to blends of tricolor phosphors. However, it is a challenge create high CRI white light from single-doped activator. Here, we present (Ra = 91) phosphor, Sr5(PO4)3-x(BO3)xCl:Eu2+, composed Sr5(PO4)3Cl the beginning member Sr5(BO3)3Cl end member. This work utilized solid-solution method, tunable Eu2+ emission was achieved....
A series of single-phased (Sr3-x,Ca1-y-z,Ba)(PO4)3Cl (SCBPO_Cl):xEu(2+), yTb(3+), zMn(2+) phosphors were synthesized by high-temperature solid-state reaction, and luminescent properties these investigated means photoluminescence microcathode luminescence (μ-CL). Under UV excitation, white-light emission was obtained from triactivated SCBPO_Cl via combining three bands centered at 450, 543, 570 nm contributed Eu(2+), Tb(3+), Mn(2+), respectively. White-light with the is further demonstrated...
Highly ordered mesoporous SiC materials were prepared by infiltrating viscous liquid preceramic polymer, allylhydridopolycarbosilane, into two types of surface modified nanoporous silica templates: SBA-15 and mesocellular siliceous foam. The templates subsequently etched off after pyrolysis at 1000 degrees C under nitrogen atmosphere with the resultant formation structures. materials, synthesized from both possessed high Brunauer-Emmett-Teller (BET) areas in range 250-260 m(2)/g pore sizes...
Electrically pumped random lasing has been realized in Au/MgO/ZnO structures. By incorporating Ag nanoparticles, whose extinction spectrum overlaps well with the emission of structures, threshold can be decreased from 63 mA to 21 mA. The decrease attributed resonant coupling between carriers active layer structures and surface plasmon nanoparticles.
A perfect impedance match from water-rich hydrogels to an oceanic background makes hydrogel microphones ideal for long-distance, underwater acoustic reception with zero reflection. novel hydrogel-graphene transistor is thus designed work under a gate-free mode, in which sheet of graphene directly converts mechanical vibrations microstructured into electrical current. This shows that the quantum capacitance plays important role determining shift Fermi level and subsequently amplitude current...
Tunable microwave absorbers have gained significant interest due to their capability actively control microwaves. However, the existing architecture-change-based approach lacks flexibility, and active-element-based is constrained by a narrowband operation or small dynamic modulation range. Here, novel electrically tunable absorbing device (TMAD) demonstrated that can achieve tuning of average reflection amplitude between -13.0 -1.2 dB over broadband range 8-18 GHz enabled reversible metal...
Dynamic manipulation of an object's infrared radiation characteristics is a burgeoning technology with significant implications for energy and information fields. However, exploring efficient stimulus-spectral response mechanism realizing simple device structures remains formidable challenge. Here, novel dynamic emissivity regulation proposed by controlling the localized surface plasmon resonance absorption aluminum-doped zinc oxide (AZO) nanocrystals through ultraviolet...
