Eu3+-activated oxide components appear as a kind of rare-earth red phosphors that can be used for warm white light-emitting diode (LEDs). At present, it is still challenge to synthesize oxide-component with high photoluminescence quantum yields compared those nitride and fluoride phosphors. Herein, we propose Gd4.67Si3O13 silicate phosphor by the convenient high-temperature solid reaction method. These designed effectively excited either 394 nm near-ultraviolet light or 465 blue then emit at...
N-doped and In-N-codoped ZnO films were fabricated on quartz glass substrate by sol-gel spin coating. Their p-type conductivities characterized the Hall measurements, revealing low resistivities of order 10−1Ωcm. Thin-film junctions comprising an undoped layer a displayed typical rectifying characteristics, suggesting formation p-n homojunctions at interfaces.
Nanoparticles (NPs) decorated ZnO/TiO2 core/shell nanorod arrays were fabricated on transparent conductive glass substrates by sequential plasma deposition and post-annealing processes for dye-sensitized solar cells (DSSCs) applications. The NPs nanorods composed of single-crystalline ZnO nanorods, homogeneously coated thin TiO2 shells entirely covered anatase NPs. photocurrent density the composite electrode was largely enhanced due to enlarged surface area, dark current suppressed...
An anti-thermal quenching strategy is proposed to develop GdNbO 4 :Pr 3+ red phosphor, which a promising candidate for the high-performance optical temperature sensing with increasing emission intensity during heating process.
The novel sodium titanate nanoflowers were synthesized through a facile hydrothermal method. as-grown self-assembled by folded broad and thin nanosheets, which formed the assistance of ZnO nanostructure templates. crystal structure was identified to be layered NaxH2−xTi2O5·H2O, formation process proposed as follows: flower-like nanorods in alkali solution at initial stage, then nanosheets deposited on surface frameworks nanorods, finally after removal framework.
Fifteen layers’ composite YAG/Yb:YAG/YAG laser ceramic with grain size of about 5 μm was fabricated through tape casting process together vacuum sintering technology, and its microstructure, optical properties, performance were investigated. The experimental results showed that annealing in oxygen atmosphere could remove the lattice distortion improve transmittance. in‐line transmittance 83% at 800 nm. study indicated threshold pump power 5.5 W output coupler transmission 6% slope efficiency...
We dope Gd(3+) ions into Ce: YAG ceramics to induce red-shift in the photoluminescence, of which degree is proportional doping concentration. This kind ceramic, when collaborating with InGaN blue chips, proves be a promising fluorescent material white light-emitting diodes, for not only its high in-line transmittance and decent quantum yield, but also improvement color rendering ability brought by red-shift, enhances ratio red portion spectra. demonstrate that 10% optimized value...
A facile and eco-friendly ethanol-thermal method has been developed to improve the moisture resistance luminescence efficiency of Mn4+-activated fluoride phosphors using oleylamine (OAm) as an organic coating layer. The K2SiF6:Mn4+ was significantly enhanced after with internal quantum increasing from 86.2 94.2%. Additionally, being soaked in deionized water, intensity KSFM@OAm remained at 85.2% its initial value, while that non-coated KSFM decreased 15.4%. This is due formation a complete...
