A Cary 5000 (Varian) UV-Vis/NIR spectrophotometer and a Fluorolog 3 (HORIBA Jobin-Yvon) spectrofluorometer, equipped with a time-correlated single photon counter (TCSPC), were used to record the UV-Vis absorption and PL emission spectra, respectively. A “Quanta-phi” (HORIBA Jobin-Yvon, Palaiseau, France) integrated sphere coated by Spectralon was used for the evaluation of the PL emission and absolute quantum yield (QY) of the C-dots dispersed in the organic solvent and of the luminescent micellar nanostructures dispersed in aqueous solution at the excitation wavelength of 360 nm.

A Cary
5000 (Varian) UV/vis/NIR spectrophotometer and a Fluorolog 3 spectrofluorimeter
(HORIBA Jobin-Yvon) were used to record the UV–vis absorption
or PL emission spectra, respectively. PL emission absolute QY of C-Dots
and of the luminescent nanoformulations dispersed in solution was
evaluated using a “Quanta-phi” (HORIBA Jobin-Yvon) integrating
sphere coated by Spectralons. Time-correlated single photon counting
(TCSPC) measurements were performed with a FluoroHub (HORIBA Jobin-Yvon)
to investigate fluorescence lifetime of C-Dots, bare in CHCl3 dispersion and after their encapsulation in the PLGA nanoformulations.
A picosecond laser diode (NanoLED 375L) emitting τ ≈
80 ps pulses at a 1 MHz repetition rate was used as the excitation
source. The PL signals were detected by a picosecond photon counter
(TBX ps Photon Detection Module, HORIBA Jobin-Yvon) with a temporal
resolution of ∼200 ps.

Luminescence Characterization at Cryogenic Temperatures

Check if the same lab product or an alternative is used in the 5 most similar protocols
All measurements were carried out on a Horiba Jobin–Yvon Flurolog 3 equipped with a 450 W xenon lamp. Photoluminescence emission (PL) and excitation (PLE) spectra were acquired by means of R13456 PMT detector. The optimal excitation wavelength for each sample was selected to measure the emission spectra and calculate the CCT / CRI. Samples were placed in an Oxford cryostat for cooling down to 77K. PLQYs were quantified using the quanta‐phi accessory from Horiba on the Fluorolog (absolute quantum yield measurements). The CCT and CRI values were calculated from the emission spectra using a modified version of the program pspectro.[29]

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.
