Abstract

Along with quantum dots (QD), carbon dots (CDs) have attracted a lot of at-tention due to its strong optical properties and simple synthesis procedure. For decades, Aloe vera has been used for medical and cosmetic applications. Another application of Aloe vera is reported here; we have synthesized CDs from Aloe vera gel through a simple heating process. With variation of heat-ing duration, we achieved CDs with various photoluminescence (PL) proper-ties. The variation of heating duration has changed the functional group on the CDs surface and induces tuneable PL properties. In this paper, we present three types of CDs, i.e., blue, green, and yellow CDs with PL peak at wave-length of at 438, 503, and 614 nm, respectively.
