Photoluminescence
Time-resolved photoluminescence (TRPL) is a method where the sample is excited with a light pulse and then the decay in photoluminescence with respect Modulated photoluminescence is a specific method for measuring the complex frequency response of the photoluminescence signal to a sinusoidal excitation wikipedia.org

Photoluminescence properties of facial- and meridional-Ir(ppy)3 thin ...
The optical absorption and the steady-state PL spectra of fac-Ir(ppy) 3, 30% mer-Ir(ppy) 3 neat thin films are shown in Fig. 2.The transition from the ground state to a singlet excited metal-to-ligand-charge-transfer (1 MLCT) state appears around 380 nm in the absorption spectrum [6].The absorption spectra of the 30% mer-Ir(ppy) 3 neat thin film are slightly different from that of the fac-Ir ...

Effect of PPy concentration on the photoluminescence of PPy ... - Springer
Luminescent polypyrrole-polymethylmethacrylate (PPy-PMMA) blends have been obtained by bulk polymerization of MMA in presence of different concentration of PPy nanowires. The PPy nanowires are distributed over the rock-like features of PMMA as observed from SEM images. Raman spectra indicate the formation of blend. PPy-PMMA blends exhibit high photoluminescence emission intensity though ...

Fluorescence intermittency in colloidal nanocrystals
Blinking colloidal nanocrystals is a phenomenon observed during studies of single colloidal nanocrystals that show that they randomly turn their photoluminescence So photoluminescence is almost entirely suppressed in charged nanocrystals. wikipedia.org
