【聚合物包裹的上轉(zhuǎn)換熒光納米顆?!浚?/p>
運用聚合物包裹的方法,在解決水溶性和功能化修飾時,提高了其生物相容性。但是這種方法比較復雜,必須設計出兩親性的高分子,或者嚴格控制其表面電荷,多次反復離心洗滌,對樣品的穩(wěn)定性造成一定的影響。
西安瑞禧生物科技有限公司可以提供有聚合物聚乙二醇包裹的上轉(zhuǎn)換熒光納米顆粒產(chǎn)品:PEG修飾的稀土摻雜的上轉(zhuǎn)換熒光納米顆粒,發(fā)射波長:紅、綠、藍可選,顆粒直徑:30-60nm
【二氧化硅包裹的上轉(zhuǎn)換熒光納米顆?!浚?/p>
二氧化硅包裹的上轉(zhuǎn)換熒光納米顆粒,包裹后的納米粒子具有很好的水溶性和生物相容性,廣泛應用于生物醫(yī)學等領(lǐng)域中。
西安瑞禧生物科技有限公司可以提供有二氧化硅包裹的上轉(zhuǎn)換熒光納米顆粒產(chǎn)品:SiO2修飾的稀土摻雜的上轉(zhuǎn)換熒光納米顆粒,發(fā)射波長:紅、綠、藍可選,顆粒直徑:50-100nm
上轉(zhuǎn)換發(fā)光是基于雙光子或多光子過程,發(fā)光中心相繼吸收兩個或者多個光子,經(jīng)過無輻射弛豫達到發(fā)光能級,從而躍遷至基態(tài)產(chǎn)生短波長光子,即將低頻率激發(fā)光轉(zhuǎn)換成高頻率發(fā)射光。
影響稀土氟化物納米材料發(fā)光性能的因素主要是基質(zhì)材料、敏化劑和激活劑。目前氟化物基質(zhì)材料研究的主要是XLnF4和LnF3,其中zui為常見的是NaYF4和LaF3,聲子能均小于400cm-1,有利于提供合適的晶體場,降低無輻射躍遷的幾率,同時激活劑容易進行摻雜。稀土離子在氟化物中具有較長的壽命,形成更多的亞穩(wěn)能級,產(chǎn)生豐富的能級躍遷。摻雜離子對上轉(zhuǎn)換的發(fā)光扮演著極為關(guān)鍵的角色,當前研究主要集中在Er3+、Tm3+、Ho3+摻雜。稀土Yb3+的激發(fā)光波長是980nm,吸收截面大,是zui為常用且有效的上轉(zhuǎn)換敏化劑。當Yb3+和其它稀土離子共摻雜到材料中,激發(fā)Yb3+離子,能量傳遞引起光子疊加效應使得上轉(zhuǎn)換發(fā)光效率大大提高。
