一、引言目前显示管用蓝色荧光粉是由 ZnS:Ag和长余辉 P39、P27混合而成。由于这一荧光粉是浅蓝色的发光,所以希望能进行色纯度好的荧光粉的开发工作。作为色纯度好的长余辉荧光粉已发表的有 ZnS:Ag、Cl、Ca,但 Ga 的加入使粉的亮度降低,因此期望开展高亮度荧光粉的研究。  相似文献

We have investigated the mechanism of phase transformation from ZnS to hexagonal ZnO by hightemperature thermal annealing. The ZnS thin films were grown on Si(001) substrate by thermal evaporation system using ZnS powder as source material. The grown films were annealed at different temperatures and characterized by X-ray diffraction(XRD), photoluminescence(PL), four-point probe, scanning electron microscope(SEM) and energy dispersive X-ray diffraction(EDX). The results demonstrated that as-deposited ZnS film has mixed phases but high-temperature annealing leads to transition from ZnS to ZnO. The observed result can be explained as a twostep process:(1) high-energy O atoms replaced S atoms in lattice during annealing process, and(2) S atoms diffused into substrate and/or diffused out of the sample. The dissociation energy of ZnS calculated from the Arrhenius plot of 1000/T versus log(resistivity) was found to be 3.1 eV. PL spectra of as-grown sample exhibits a characteristic green emission at 2.4 eV of ZnS but annealed samples consist of band-to-band and defect emission of ZnO at 3.29 eV and 2.5 eV respectively. SEM and EDX measurements were additionally performed to strengthen the argument.  相似文献

Organic solar cells with stacked bulk heterojunction(BHJ) are investigated based on conjugated polymer.By using the solution spin-coating method,Poly [2-methoxy,5-(2' -ethyl-hexyloxy) -1,4-phenylene vinylene](MEH-PPV) and ZnO nanoparticles(50 nm) are mixed as the optical sense layer.Ag is used as inter-layer to connect the upper BHJ cell and the lower cell.The structures are ITO/PEDOT:PSS/MEH-PPV /Ag / MEH-PPV:ZnO /Al.The open circuit voltage(VOC) of a stacked cell is about 3.7 times of that of an individual organic solar cell(ITO/PEDOT:PSS/MEH-PPV /Al).The short circuit current(JSC) of a stacked cell is increased by about 1.6 times of that of individual one.  相似文献
