Matrix‐free room‐temperature phosphorescence graphitic carbon nitride quantum dots based on halogen bond interactions for security applications

open access: yesNano Select, 2022
Herein, we first designed a one‐step strategy to achieve matrix‐free room temperature phosphorescence (RTP) materials by low temperature solid phase synthesis, using sodium citrate as carbon source and urea as nitrogen source.

Induction of long-lived room temperature phosphorescence of carbon dots by water in hydrogen-bonded matrices

open access: yesNature Communications, 2018
A long phosphorescence lifetime is desirable for imaging and detection, however, phosphorescence is often quenched in aqueous environments limiting applications. Here, Li et al.

Biophosphorescence in fluorescent millipedes (Diplopoda: Xystodesmidae) and its relationships with bioluminescence

open access: yesScientific Reports, 2023
Three types of luminescence have been reported in living organisms: bioluminescence (BL), ultraweak chemiluminescence and biofluorescence (FL). In millipedes, both BL and FL have been reported in Motyxia sequoiae and related Xystodesmidae species ...
