Carbon quantum dots Semiconductor Starch Microwave Luminescence Link to publisher's homepage at http://ijneam.unimap.edu.my/ Tunable luminescence carbon dots (C-dots) were prepared through microwaveassisted carbonization of aqueous starch suspension mediated by sulfuric and phosphoric acids respectively as surface passivating agents. The as-prepared C-dots showed green, blue and yellow luminescence under 365nm UV light. The C-dots were further characterized by UV-Vis, FTIR, and band gap determination. Fourier transform infrared spectroscopy (FTIR) studies revealed bands at 3460 cm-1 (OH), 2979 cm-1 1708 cm-1 (C=O), 1188 and 1040cm-1 (C-O), and 1397 cm-1 (C=C) indicative of the graphitic nature of the carbon. The UV-Vis showed blue shifted absorption bands, while the band gap calculated revealed narrow sizing of the C-dots in the semiconductor range. The results suggest that this approach may serve as a facile route to colour tunable photoluminescent C-dot materials with potential biological applications. 2017-09-28T07:27:54Z 2017-09-28T07:27:54Z 2017 Article International Journal of Nanoelectronics and Materials, vol.10 (1), 2017, pages 11-20 1985-5761 (Printed) 1997-4434 (Online) http://dspace.unimap.edu.my:80/xmlui/handle/123456789/49811 en Universiti Malaysia Perlis (UniMAP)
