Evidence Details
In a typical synthesis, 80 mg of flour was sealed and heated in a computer-controlled XH-800C microwave digestion system ... at 180 °C for a period of 20 min.
Its QY is determined to be 5.4% ... The QY is dropped to 1.5% after addition of 40 μM Hg2+.
The resultant C-dots exhibit high sensitivity and selectivity toward Hg2+ with a detection limit as low as 0.5 nM and a linear range of 0.0005–0.01 μM.
Time: 20 min / 10 min / 48 h
Particle size: -4 nm
Additional source evidence: source values include 1-4 nm.
