The UV–visible
absorption spectra were recorded using a Varian Cary 300 UV–vis
absorption spectrophotometer. The PL spectra were measured on a Varian
Cary Eclipse spectrophotometer using an excitation wavelength (λex) of 350 nm for all of the samples. Samples were prepared
by diluting NC solutions in toluene, in quartz cuvettes with a path
length of 1 cm.

Optical absorption
spectra were collected on a Varian Cary 300 UV–vis absorption
spectrophotometer, while PL spectra were recorded by a Varian Cary
Eclipse spectrophotometer using an excitation wavelength at 370 nm
for all of the samples. The NC solutions were diluted in toluene in
quartz cuvettes (path length = 1 cm) to a maximum optical density
below 1.0, to minimize self-absorption effects. The time-resolved
PL measurements were performed on an Edinburgh FLS900 fluorescence
spectrometer equipped with a time-correlated single photon counting
unit coupled with an Edinburgh Instruments EPL-510 pulsed laser diodes
(λexc = 372 nm, pulse width = 68.8 ps, and λexc = 508.2 nm, pulse width = 177.0 ps). Data analysis was
carried out using DecayFit software.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
