摘要題目碳量子點(diǎn)的合成、性質(zhì)及應(yīng)用

1、第二屆“納米科學(xué)前沿論壇” 分子納米結(jié)構(gòu)與納米技術(shù)實(shí)驗(yàn)室摘要題目 碳量子點(diǎn)的合成、性質(zhì)及應(yīng)用 報(bào)告人： 黃佩佩黃佩佩，女，1988年3月出生，山東菏澤人，2011年9月考入中科院化學(xué)研究所，現(xiàn)在中科院化學(xué)所分子納米科學(xué)與納米技術(shù)實(shí)驗(yàn)室宋衛(wèi)國研究員課題組從事納米吸附材料合成及對(duì)重金屬離子吸附性能研究的工作。摘要內(nèi)容(Introduction)量子點(diǎn)，又稱作半導(dǎo)體納米微晶體，在光學(xué)、磁學(xué)、催化學(xué)、生物醫(yī)藥及功能性材料等領(lǐng)域有著廣泛的應(yīng)用前景1-5。但是，該類材料在高濃度或紫外照射下易分解，會(huì)釋放出致命的重金屬離子，對(duì)生物體及環(huán)境造成潛在的威脅，因此尋找具有類似光學(xué)性質(zhì)的良性納米材料成為了該領(lǐng)域科研

2、工作者的研究焦點(diǎn)6-9,11。碳作為地球上含量最豐富的元素之一，其新的存在形式-碳量子點(diǎn)，不僅能夠發(fā)射穩(wěn)定的長壽命熒光還具有寬的激發(fā)波長范圍，可作為生物標(biāo)記物對(duì)生物體進(jìn)行長時(shí)間及多樣品的同時(shí)檢測；而且經(jīng)表面修飾或摻雜處理后，其熒光發(fā)射量子產(chǎn)率可與高性能半導(dǎo)體量子點(diǎn)媲美；最重要的是，它較以往的熒光材料更具有生物安全性，比其他熒光標(biāo)記物對(duì)生物分子的活性干擾小。碳量子點(diǎn)的優(yōu)異性除了體現(xiàn)在生物熒光標(biāo)記方面外，通過改變引入到其表面的官能團(tuán)種類來調(diào)控其光電性質(zhì)、溶解性及與各種界面的相宜性等參數(shù)，碳量子點(diǎn)也將在制備磁共振成像的造影劑、磁數(shù)據(jù)存儲(chǔ)、光電轉(zhuǎn)換及光催化領(lǐng)域10-14大放異彩。參考文獻(xiàn)：1 Peng
