Abstract


Light-emitting display technology with the field emission (FED) and plasma (PDP), particle size distribution of the phosphor size, stability, luminous efficiency, brightness, and the conductivity of a higher demand, due to the nano-light-emitting materials possess quantum effect, surface effect and the small size effect excellent performance of its luminescence properties have a significant impact, which has become the focus of new luminescent materials. Many nanometer light emitting material, due to the special optical properties of ZnO location, such that it has become a promising optoelectronic application software and the photosensitive device candidate materials; boron rare earth aluminate luminescent material of matrix having good chemical and thermal stability, and therefore, the focus of this paper is to study the nano luminescent material of the rare-earth doped with boron aluminosilicate and zinc oxide as a substrate. This paper reviews the Luminescent Nanomaterials Research, the system introduced by the spectral theory of lanthanide ions and lanthanide-doped light-emitting nanoparticles research background, summarized and reviewed in recent years lanthanide doped light-emitting nanoparticles synthesis and surface modification the progress made and the problems facing the direction of future research summary and outlook. On this basis, we focused on the field emission display (FED) and plasma (PDP) of the light-emitting materials, boron rare earth aluminate and zinc oxide nano-light-emitting materials for the study, the sol - gel method, hydrothermal , thermal solvent, shocks and other methods were successfully prepared a variety of different morphology and optical properties of nanocrystalline rare earth. Application of X-ray diffraction (XRD), field emission scanning electron microscope (SEM), photoluminescence (PL) spectroscopy, energy dispersive spectroscopy (EDX), luminescence decay curves and life means the synthesis conditions and the concentration of dopant ions of rare earth doped nanoparticle crystal structure, morphology and size, solubility and luminescent properties of dopant ions, and achieved a number of important conclusions and innovative achievements to become a great, rare-earth-doped nano-light-emitting material The prospects for the development of new light-emitting materials laid a solid foundation. Explore synthesis of SrAl 2 B 2 O 7 of : the Eu 3 , SrLi x Al 2 B 2 O 7 : Eu 3 5%, SrNa x Al 2 B O 7 : Eu 3 5%, SrAl 2 B 2 O 7 : Tb 3 , SrAl 2 B 2 O 7 < / sub>: Ce 3 , Tb 3 , YAl 3 (BO 3 ) 4 : Eu 3 , Dy 3 , YAl 3 (BO 3 ) 4 : Eu 2 , Dy 3 , YBO 3 : Eu 3 , RE, ZnO: Eu 3 system, the nature of the rare earth ion concentration and synthesis temperature and substrate composition luminescent properties. A new approach to preparation of ZnO nanorods and nano-flowers, prepared nanorods uniform size with a diameter of 65-85nm, length of 2 uM. The sol-gel method, thermal solvent method, hydrothermal method was successfully prepared with different morphologies of zinc oxide, the first to investigate the relationship between the microstructure, morphology and macro-luminescent properties of zinc oxide.
