In this study, it was aimed to obtain graphene quantum
dots (GQDs) from dried pine leaf (DPL) (peanut pine (Cedruslibani,
Pinusnigra)). Decomposition temperatures of the dried pine leaf were determined
by DTA-TGA analysis in nitrogen atmosphere. DPL was subjected to carbonization
in an ash furnace for 6 hours in air,
at temperatures of 250, 300, 350 0C. The materials obtained from
the thermal process are characterized using FT-IR; XRD; SEM-EDAX; UV-VIS and
Fluorescence spectrometer analysis. When dissolved in deionized water, these materials
emits blue fluorescence under UV-A and UV-C excitation. The emission and excitation
peaks are very sharp indicating an homogeneous particle distribution of GQDs’s
in the water. When the analysis results were examined, it was observed that the
substance obtained as a result of the carbonization process at 350 0C
for 6 hours was compatible with GQDs data in the literature.
