发光(guang)(guang)材(cai)(cai)料(liao)(liao)是(shi)照明/显示(shi)、荧(ying)光(guang)(guang)成(cheng)(cheng)(cheng)像、激光(guang)(guang)等技术(shu)发展的基础,具有巨大的市(shi)场需求。随着人类对环境和(he)健康(kang)安全的不断(duan)重视,开发环保、无毒(du)、低能耗、可持续生产(chan)、稳定(ding)、高效的新型(xing)发光(guang)(guang)材(cai)(cai)料(liao)(liao)变得尤为重要。荧(ying)光(guang)(guang)碳(tan)(tan)点是(shi)一种新型(xing)的准零维碳(tan)(tan)纳米材(cai)(cai)料(liao)(liao)。与现有的荧(ying)光(guang)(guang)材(cai)(cai)料(liao)(liao)(有机(ji)、稀土、钙(gai)钛矿、胶体量子点)相比,碳(tan)(tan)点具有成(cheng)(cheng)(cheng)本(ben)低、环境友好、颜(yan)色可调、荧(ying)光(guang)(guang)稳定(ding)等优(you)点,同时适合大面积溶液加工。碳(tan)(tan)点已(yi)成(cheng)(cheng)(cheng)功作为发光(guang)(guang)活性层应(ying)(ying)用于(yu)电(dian)致发光(guang)(guang)二极管(LEDs)中,是(shi)应(ying)(ying)用于(yu)新一代的平(ping)板显示(shi)和(he)固态照明技术(shu)的潜在材(cai)(cai)料(liao)(liao)。

近(jin)日,64体(ti)育软物质科学与工程(cheng)高精尖创新(xin)中(zhong)(zhong)心(xin)谭占(zhan)鳌教授课(ke)题组(zu)在前期(qi)研究(jiu)工作的(de)(de)(de)(de)(de)基础上,系统总(zong)结、讨论(lun)了(le)(le)碳(tan)(tan)点(dian)(dian)(dian)在电(dian)(dian)(dian)致(zhi)(zhi)发(fa)(fa)(fa)光(guang)(guang)二极(ji)管(guan)领域的(de)(de)(de)(de)(de)研究(jiu)进展(zhan)。该综(zong)述介绍了(le)(le)碳(tan)(tan)点(dian)(dian)(dian)电(dian)(dian)(dian)致(zhi)(zhi)发(fa)(fa)(fa)光(guang)(guang)二极(ji)管(guan)的(de)(de)(de)(de)(de)器件(jian)(jian)(jian)(jian)结构和工作原理,总(zong)结了(le)(le)目(mu)前应用于电(dian)(dian)(dian)致(zhi)(zhi)LEDs中(zhong)(zhong)碳(tan)(tan)点(dian)(dian)(dian)的(de)(de)(de)(de)(de)制(zhi)备方法,详细地讨论(lun)了(le)(le)碳(tan)(tan)点(dian)(dian)(dian)作为(wei)发(fa)(fa)(fa)光(guang)(guang)层(ceng)(包(bao)括(kuo)(kuo)掺(chan)(chan)杂和非(fei)掺(chan)(chan)杂体(ti)系)以及(ji)界(jie)面传输(shu)层(ceng)在电(dian)(dian)(dian)致(zhi)(zhi)LEDs中(zhong)(zhong)的(de)(de)(de)(de)(de)研究(jiu)近(jin)况。此外,针对目(mu)前碳(tan)(tan)点(dian)(dian)(dian)电(dian)(dian)(dian)致(zhi)(zhi)LEDs整体(ti)器件(jian)(jian)(jian)(jian)性(xing)能(neng)(neng)较(jiao)差的(de)(de)(de)(de)(de)问题,作者从高效碳(tan)(tan)点(dian)(dian)(dian)的(de)(de)(de)(de)(de)设计合(he)成(包(bao)括(kuo)(kuo)固(gu)态发(fa)(fa)(fa)光(guang)(guang)碳(tan)(tan)点(dian)(dian)(dian)、磷光(guang)(guang)碳(tan)(tan)点(dian)(dian)(dian)、热激活延迟荧(ying)光(guang)(guang)碳(tan)(tan)点(dian)(dian)(dian))和器件(jian)(jian)(jian)(jian)结构工程(cheng)的(de)(de)(de)(de)(de)角度出(chu)发(fa)(fa)(fa),提出(chu)了(le)(le)构筑(zhu)高性(xing)能(neng)(neng)碳(tan)(tan)点(dian)(dian)(dian)电(dian)(dian)(dian)致(zhi)(zhi)器件(jian)(jian)(jian)(jian)的(de)(de)(de)(de)(de)可行性(xing)策略。最后,作者分析并展(zhan)望了(le)(le)碳(tan)(tan)点(dian)(dian)(dian)电(dian)(dian)(dian)致(zhi)(zhi)发(fa)(fa)(fa)光(guang)(guang)器件(jian)(jian)(jian)(jian)未(wei)来(lai)的(de)(de)(de)(de)(de)发(fa)(fa)(fa)展(zhan)前景(jing)以及(ji)可能(neng)(neng)面临(lin)的(de)(de)(de)(de)(de)挑战。该论(lun)文旨在为(wei)构筑(zhu)新(xin)一(yi)(yi)代高性(xing)能(neng)(neng)电(dian)(dian)(dian)致(zhi)(zhi)发(fa)(fa)(fa)光(guang)(guang)器件(jian)(jian)(jian)(jian)提供一(yi)(yi)定(ding)的(de)(de)(de)(de)(de)指(zhi)导与参考价值。
