Scientometric review of global squaraine dye research

Abstract

Squaraines are organic dyes with a wide range of applications ranging from solar cells to medical imaging. The main objective of this study is to analyse the pattern of squaraine dyes research scientometrically. The study, based on the data collected from citation databases, Web of Science (WoS), and Scopus, reveals that the research on squaraine dyes shows a positive growth rate. The highest number of publications are from the United States of America, followed by China. Three Asian countries, China, Japan, and India, accounted for about half of all global research output. The most productive institute is CSIR-NIIST-India in terms of the number of papers published and citations received per paper (CPP) among the top fifteen institutes. In addition to solar cell-related applications of squaraine dyes, bioimaging, drug delivery, and photodynamic therapy are also receiving sufficient attention from researchers. Since the number of studies and researchers involved in this field has been found to be less, efforts should be undertaken to strengthen the research on squaraine dyes to explore the wide range of its applications
