【摘要】：無機(jī)納米材料的形貌、尺寸及其微觀結(jié)構(gòu)將會(huì)影響其性質(zhì)和應(yīng)用,具有一定形貌和微觀結(jié)構(gòu)的無機(jī)納米材料(如：納米線、納米棒、納米束等)的合成及其性能的表征也將影響新型無機(jī)功能材料的研究。由于稀土離子獨(dú)特的電子層結(jié)構(gòu),使得稀土發(fā)光材料廣泛用于照明、顯示、檢測(cè)三大領(lǐng)域。氟化物因其多樣性的結(jié)構(gòu)特點(diǎn)和特殊的物理化學(xué)特性,成為了優(yōu)良的發(fā)光基質(zhì)。因此,利用溶劑熱法制備稀土離子摻雜的稀土氟化物納米棒及其性質(zhì)研究,將是一個(gè)重要而又新穎的研究課題。本文采用XRD、FESEML、EDS和熒光光譜等分析技術(shù)對(duì)樣品進(jìn)行了系統(tǒng)地表征,結(jié)果表明,所制備的稀土離子摻雜的稀土氟化物納米棒均具有良好的發(fā)光性質(zhì),獲得了一些有意義的結(jié)果,為稀土納米發(fā)光材料的進(jìn)一步深入研究奠定了一定基礎(chǔ)。主要研究?jī)?nèi)容歸納如下： 1、利用溶劑熱法制備了La(OH)3:Eu3+納米棒,選用NH4HF2作為氟源,利用固相反應(yīng),制備了LaF3:Eu3+納米發(fā)光材料,并研究了其發(fā)光性能。 2、PEG輔助的溶劑熱法,制備出了Y(OH)3:Eu3+納米棒。選用NH4HF2作為氟源,利用固相反應(yīng),制備了YF3:Eu3+納米發(fā)光材料,并研究了其發(fā)光性能。 3、利用溶劑熱法制備了Y(OH)3:Tb3+納米棒,選用NH4HF2作為氟源,利用固相反應(yīng),制備了YF3:Tb3+納米發(fā)光材料,并研究了其發(fā)光性能。 4、利用溶劑熱法制備了Gd(OH)3:Eu3+納米棒,選用NH4HF2作為氟源,利用固相反應(yīng),制備了GdF3:Eu3+納米發(fā)光材料,并研究了其發(fā)光性能。
[Abstract]:The morphology, size and microstructure of inorganic nanomaterials will affect their properties and applications. Inorganic nanomaterials with certain morphology and microstructure (such as nanowires, nanorods, etc.) The synthesis and characterization of nanobeams will also affect the study of new inorganic functional materials. Due to the unique electronic structure of rare earth ions, rare earth luminescent materials are widely used in lighting, display and detection. Because of its diverse structure and special physical and chemical properties, fluoride has become an excellent luminescent substrate. Therefore, the preparation and properties of rare earth fluoride nanorods doped with rare earth ions by solvothermal method will be an important and novel research topic. In this paper, the samples were characterized systematically by means of XRDX FESEML EDS and fluorescence spectra. The results show that the rare earth ions doped rare earth fluoride nanorods have good luminescence properties, and some meaningful results have been obtained. It lays a foundation for the further study of rare earth nano luminescent materials. The main research contents are summarized as follows: 1. La(OH)3:Eu3 nanorods were prepared by solvothermal method, NH4HF2 was selected as fluorine source, LaF3:Eu3 nanoluminescence materials were prepared by solid state reaction, and their luminescence properties were studied. Y(OH)3:Eu3 nanorods were prepared by Y(OH)3:Eu3-assisted solvothermal method. Using NH4HF2 as fluorine source, YF3:Eu3 nanocrystalline luminescent materials were prepared by solid state reaction and their luminescence properties were studied. 3. Y(OH)3:Tb3 nanorods were prepared by solvothermal method, NH4HF2 was selected as fluorine source, YF3:Tb3 nanoluminescence materials were prepared by solid state reaction, and their luminescence properties were studied. (4) Gd(OH)3:Eu3 nanorods were prepared by solvothermal method, NH4HF2 was selected as fluorine source, GdF3:Eu3 nanoluminescence materials were prepared by solid state reaction, and their luminescence properties were studied.
