A Bibliometric Analysis of Carbon Dots in Sensors Application

Abstract

Abstract The exponential increase in carbonaceous-based research has prompted the scientific community to apply it into numerous value-added applications. This paper aimed to systematically analyzed the comprehensive contributions clusters of publications per year, country-, institution, authors, and keywords-wise by using a quantitative review technique called bibliometric analysis. The data was retrieved from the Scopus database to identify the overall scientific trend results with the keyword of "carbon dots as a sensor" from 2010 to 2020. The VOSviewer, WordItOut, and Datawrapper are selected as tools for bibliometric analysis and data visualization. In this work, the total citations from the Scopus Core Set and the total citations in the most recent year have only been used for the assessment of highly cited papers. The results showed that after 2014, the number of publications increased significantly with the work-related with “carbon dots as sensor”. Thus, comprehensive journal like the Angewandte Chemie - International Edition was most popular in publishing article contributing to almost 6.39% in the research area. The country-wise analysis revealed that China accounted for more than 67.18% of the articles published followed by 6.24% and 6.13%. Lastly, keyword cluster analysis revealed five major research hotspots for future discussion. Thus, this analysis provides an important starting point for further studies on research concerning "carbon dots as a sensor" direction for positive development in research area.
