Reduction of reabsorption effects in scintillators by employing solutes with large stokes shifts

Experimental and theoretical studies of electronic energy states of methyl benzoate derivatives

“…Table 1 assembles the wavelengths of the respective absorption and emission band maxima determined in solutions of different polarity. The absorption spectra of all molecules under study possess three absorption bands, which will be labelled as C, B and A, respectively [38]. They correspond to the benzene bands:…”

“…It is necessary to note that this class of studied molecules is interesting for two reasons: because they provide means of studying the general theory of CT and PT processes, and because some of those can be useful as molecular probes in solvation dynamics [30,31], lasing medium in protontransfer lasers [32,33] and tribo-active materials in dry xerographic toners and metal ion sensors [34][35][36][37][38].…”

Scintillation counters in modern high-energy physics experiments (Review)

“…The commonly used wavelength shifters are Y11, POPOP, and 3HF (3 hydroxyflavone) with the Stokes shifts as large as 190 nm for 3HF [19] and 60 nm for POPOP (Fig. 4a) [20] and Y11 (Fig.…”

Novel 6-(1H-benzo[d]imidazol-2-yl) benzo[a]phenazin-5-ol Derivatives with Dual Emission and Large Stokes Shift Synthesis, Photophysical Properties and Computational Studies

“…The molecules exhibiting ESIPT have been exploited as model systems for the study of the proton transfer reaction dynamics [3,4]. The ESIPT reaction, a fast enol-to-keto or (amine-to-imine) prototropy occurring in the excited states of intramolecularly hydrogen-bonded molecules, has been extensively investigated because of its fundamental interest in photophysical properties and potential applications in luminescent materials [5], photo patterning [6], chemosensors [7], proton transfer laser [8], photo stabilizers [9,10], molecular logic gates [11], molecular probes [12], metal ion sensors [13,14], radiation hard-scintillator counters [15], and organic light emitting devices (OLEDs) [16,17], The ESIPT compounds have also drawn much attention due to their potential applications in optical devices [18,19] that may take advantage of the salient properties of the ESIPT compounds such as the ultra-fast reaction rate and extremely large fluorescence Stokes shift [20] compared to the normal fluorophores such as fluorescein, rhodamine or boron dipyrromethene (BODIPY), coumarin [21][22][23].…”
