【摘要】：采用固相反應(yīng)法制備了鏑銪共摻硅酸鹽(Ca_2MgSi_2O_7∶Eu,Dy)長(zhǎng)余輝熒光粉材料,并制備成熒光涂料,研究其應(yīng)用特性。通過(guò)X射線(xiàn)衍射、熒光光譜、余輝衰減對(duì)材料的晶型及發(fā)光特性進(jìn)行了研究。結(jié)果表明,熒光粉的晶體結(jié)構(gòu)沒(méi)有隨著稀土離子的摻入而發(fā)生變化,在382 nm處熒光粉存在最強(qiáng)激發(fā)峰,發(fā)射光譜最強(qiáng)發(fā)射峰為531 nm,余輝時(shí)間長(zhǎng)達(dá)15 h。隨著涂料中熒光粉摻入濃度的提高,涂料涂層的熒光強(qiáng)度、黏度和固化后硬度明顯增強(qiáng),吸水率顯著下降�；贑a_2MgSi_2O_7∶Eu,Dy材料所制備的熒光涂料具有余輝時(shí)間長(zhǎng)、耐候性?xún)?yōu)等特點(diǎn),在熒光涂料領(lǐng)域具有一定的應(yīng)用潛力。
[Abstract]:The long afterglow phosphors of dysprosium europium co-doped silicate (Ca2MgSiS _ 2O _ 7: EU _ (Dy) were prepared by solid state reaction. The fluorescent coatings were prepared and their application characteristics were studied. The crystal structure and luminescence characteristics of the materials were studied by X-ray diffraction, fluorescence spectra and afterglow decay. The results show that the crystal structure of the phosphors does not change with the doping of rare earth ions. There is the strongest excitation peak at 382 nm, the strongest emission peak is 531 nm, and the afterglow time is 15 h. With the increase of the concentration of phosphor in the coating, the fluorescence intensity, viscosity and hardness of the coating increased obviously, and the water absorption decreased significantly. The fluorescent coatings based on Ca2MgSi2O7: EuDy have long afterglow time, excellent weathering resistance, and have a certain application potential in the field of fluorescent coatings.
