稀土上轉(zhuǎn)換納米材料簡(jiǎn)介及熒光發(fā)光性能
【稀土上轉(zhuǎn)換納米材料簡(jiǎn)介】:
1.定義:上轉(zhuǎn)換發(fā)光材料是一種近紅外光激發(fā)下能夠產(chǎn)出紫外/可見(jiàn)光的材料,即將紅外低能光子轉(zhuǎn)換為紫外/可見(jiàn)高能光子的發(fā)光材料。其特點(diǎn)是所吸收的光子能量低于發(fā)射的光子能量,故稱為上轉(zhuǎn)換發(fā)光,又稱反斯托克斯發(fā)光。
2.優(yōu)勢(shì):稀土上轉(zhuǎn)換發(fā)光材料具有低毒性、化學(xué)穩(wěn)定性高、光穩(wěn)定性優(yōu)異、發(fā)射帶窄、發(fā)光壽命長(zhǎng)等優(yōu)點(diǎn)。同時(shí),其激發(fā)光源近紅外光(980 nm或808 nm)具有光穿透力強(qiáng)、對(duì)生物組織幾乎無(wú)損傷、無(wú)背景熒光等特點(diǎn)。
3.外觀形貌及光學(xué)照片
固體為白色粉末(可分散在極性溶劑或非極性溶劑中)
4.應(yīng)用:生物成像、光動(dòng)力學(xué)治療、光催化、三維顯示、藥物釋放等。在以上實(shí)際應(yīng)用中,稀土上轉(zhuǎn)換納米材料主要起到了光源轉(zhuǎn)換的作用。例如:在生物成像中,主要實(shí)現(xiàn)了由近紅外光激發(fā)產(chǎn)生可見(jiàn)紅、綠、藍(lán)等顏色的光,進(jìn)而對(duì)生物細(xì)胞進(jìn)行標(biāo)識(shí);在光催化領(lǐng)域,實(shí)現(xiàn)了由近紅外光激發(fā)產(chǎn)生紫外光,進(jìn)而對(duì)有機(jī)污染物進(jìn)行光降解;在光動(dòng)力學(xué)治療領(lǐng)域,主要利用稀土上轉(zhuǎn)換發(fā)光材料將近紅外光轉(zhuǎn)換紫外、可見(jiàn)光并與相應(yīng)的光敏劑偶聯(lián),從而產(chǎn)生單線態(tài)氧,終實(shí)現(xiàn)對(duì)癌細(xì)胞的診治;在藥物釋放方面,主要利用稀土上轉(zhuǎn)換納米材料與孔材料相結(jié)合,通過(guò)近紅外光控實(shí)現(xiàn)對(duì)靶向藥物的可控釋放。
