Figure 4: Single-nanocrystal photoluminescence spectra and the shake-up process. a , Photoluminescence spectra of five selected single CdZnSe/ZnSe nanocrystals. b , Photoluminescence spectrum of a ...

Photoluminescence spectra were recorded using a HORIBA FluoroMax® spectrofluorometer. The emission spectra were performed with an excitation wavelength of 475 nm and slit-widths of 2.0 nm. All spectra ...

Photoluminescence characterization of the WS 2 flake. (Left) PL reference spectra. (Right) 2D PL map based on decomposition on reference spectra. The characteristic spectra shown on Figure 2 for the ...

Quantum dots (QDs) have a large number of application in biolabeling, biosensing, memory devices and laser light sources. It can be seen that alloyed CdSeTe quantum dots possess a non-linear change in ...

Full luminescence spectra was acquired at every sample position while the single photon counting APD was employed to measure the time resolved luminescence decay at selected spectral positions. Owing ...

(c) Photoluminescence spectra from ion-gel gated graphene as a function of chemical potential µ. The excitation wavelength and incident fluence were 1400 nm (0.89 eV) and 3.7 J/m 2. The sharp peak at ...

Photoluminescence quantum yield (PLQY) is a key parameter that quantifies the efficiency of light emission in luminescent materials, crucial for applications in LEDs, ... By measuring the absorbance ...
