Abstract

Highly luminescent carbon quantum dot with Blue-Violet emission was synthesized from camphor by simple combustion followed by sonication. Prepared carbon dots were characterized by transmission electron microscopy, uv absorption spectroscopy, Fourier transform infrared spectroscopy and photoluminescence spectroscopy. The synthesized carbon dots have very small size of less than 10nm. Fluorescence study of the prepared carbon dots revealed that it has an excitation independent emission in the near-uv wavelengths with a fluorescence red shift from 385nm to 430 nm by ageing.Highly luminescent carbon quantum dot with Blue-Violet emission was synthesized from camphor by simple combustion followed by sonication. Prepared carbon dots were characterized by transmission electron microscopy, uv absorption spectroscopy, Fourier transform infrared spectroscopy and photoluminescence spectroscopy. The synthesized carbon dots have very small size of less than 10nm. Fluorescence study of the prepared carbon dots revealed that it has an excitation independent emission in the near-uv wavelengths with a fluorescence red shift from 385nm to 430 nm by ageing.

高强度的蓝紫色发光碳点来源于樟脑烟尘

以樟脑为原料，经简单燃烧-超声合成了具有蓝紫色发光特性的高发光碳量子点。采用透射电子显微镜、紫外吸收光谱、傅里叶变换红外光谱和光致发光光谱对制备的碳点进行了表征。合成的碳点尺寸非常小，小于10nm。对制备的碳点进行了荧光研究，发现其在近紫外波段具有激发无关的发光，随着老化，其荧光红移从385nm到430nm。以樟脑为原料，经简单燃烧-超声合成了具有蓝紫色发光特性的高发光碳量子点。采用透射电子显微镜、紫外吸收光谱、傅里叶变换红外光谱和光致发光光谱对制备的碳点进行了表征。合成的碳点尺寸非常小，小于10nm。对制备的碳点进行了荧光研究，发现其在近紫外波段具有激发无关的发光，随着老化，其荧光红移从385nm到430nm。
