Confined-domain crosslink-enhanced emission effect in carbonized polymer dots

Confined-domain crosslink-enhanced emission effect was first studied to reveal the photoluminescence mechanism of carbonized polymer dots (CPDs). A general strategy was exploited to synthesize CPDs exhibiting tunable photoluminescence properties.

Ultraviolet phosphorescent carbon nanodots

Ultraviolet high-energy photons of phosphorescent carbon dots for antibacterial applications. Herein, the UV phosphorescent CNDs were achieved by decreasing conjugation size and spatial confinement. As a demonstration, the CNDs are used to inactivate gram-negative/positive bacteria.

Formation and fluorescent mechanism of red emissive carbon dots from o-phenylenediamine and catechol system

The fluorophore source of red emissive oPD&CAT system CDs is the 5,14-dihydroquinoxalino[2,3-b] phenazine (DHQP), formed in the initial reaction stage. Subsequently, the DHQP was connected with carbon core. The excited electrons of the molecular state can transfer into the energy level of CDs, which leads to UV excitation red emissive intensity decreased.
