摘要：
In this article, the luminescence feature of sugar derived carbon dots is exploited for the fabrication of luminescent marker and pH sensor. A new environment benign material, Gum Arabic (GA) is introduced as a potential binder for luminescent markers for the first time. The marker was found to be highly photo stable and exhibited considerable adherence over a wide range of substrates. The luminescence intensity of the system is sequentially decreased with increment in pH of the medium, which enabled pH sensing using the system in the wide range of -10. 2-10.
