“…Perylene diimide (PDI) dyes have drawn attention for many years as efficient dopants for transparent polymers due to their fluorescence properties as industrial pigments [14]. PDI is a polycyclic aromatic hydrocarbon with the chemical formula C 20 H 12 ; the dye derivatives of this molecule have been studied for their range of useful properties including high stability, intense absorbance in the UV/visible range, high fluorescence quantum yield up to 100%, and being excellent n-type semiconductors [15,16,17,18,19]. These properties have led to the exploitation of perylenes in various applications such as organic field-effect transistors, thin-film transistors, complex supramolecular systems, and, increasingly, organic photovoltaics (OPVs) [20,21,22].…”

Luminescent polymethylmethacrylate (PMMA) films were prepared by the solvent-casting technique from polymer solution doped with different concentrations of red perylene dyestuffs (KREMER 94720 and KREMER 94739). The effect of the dye concentration on the structure and spectroscopic properties was studied using X-ray diffraction (XRD), transmission electron microscope (TEM) optical absorption, and fluorescence spectroscopy. The optimum dye concentration of photoselective PMMA films was determined by the fluorescence spectroscopy measurements and showed the best emission properties for the doping concentration 10−3 wt % of the investigated dyes. The accelerated photostability tests showed promising stability of the prepared films towards terrestrial solar ultraviolet radiation (UVA). The results endorsed a promising application of the investigated films in photoselective greenhouse cladding applications as the optimized film fluoresces at the action spectra of special chlorophyll a.

“…Although already having reached commercial maturity and extensively researched in inorganic LED pumped systems [6][7][8], the use of external downconverters (DCs) remains surprisingly rare in WOLED research [9][10][11][12]. This approach is shown in Figure 1, in which an external material is used to absorb some of the emission from the electrically driven device, and itself them emits the remaining colours necessary to produce white light.…”

“…This broad emission also increases the range of materials that can be used as DCs, as their absorption spectra are not as tightly restricted by the emission profile of the driving OLED. Indeed, recently perylene diimides (PDIs) and perylene tetraester (PTE) derivatives have been successfully incorporated in DC systems for inorganic LEDs [7,8], as these materials displaying excellent optical properties as well as high thermal stability [13][14][15][16][17][18].…”

“…Therefore, red phosphors can be integrated into this system to improve the CRI and also to reduce the correlated color temperature (CCT) [28,38]. However, due to the limitation of rare-earth material resources and the harsh synthesis conditions involved, phosphors are targeted to be replaced by novel materials such as perovskites [39–41], organic dyes [42–43], quantum dots [44] and CDots [15,45]. Among these, CDots are a promising alternative since they are cost effective and optically feasible, making them commercially viable.…”

In this study, green-emitting nitrogen-doped carbon dots (N-CDots) were synthesized and incorporated into drop-cast composite films for use as color conversion layers in a white-LED configuration to generate white light. In order to resolve the red deficiency of this configuration, a commercial red phosphor was integrated into the system. Moreover, the N-CDots were also processed into polymer/N-CDot composite fibers, for which we determined the amount of N-CDots that yielded adequate white-light properties. Finally, we showed that white light with excellent properties could be generated by employing both of the fabricated N-CDot composites either as drop-cast films or composite fibers. Hence, N-CDots provide a promising alternative to inorganic phosphors that are commonly employed in white-LED configurations.
