• devices based on the combination of dicyanomethylene and pyranine as organic dyes supported on zinc single-layered hydroxide” [31]. In this article, two fluorescent organic dyes, dicyanomethylene and pyranine, emit visible light upon blue LED excitation and are tethered to single layer hydroxide platelets

• luminescent organic dyes in a single-layered hydroxide (SLH)-type inorganic matrix has been developed. Two fluorescent organic dyes emitting visible light upon blue LED excitation were investigated in this study: dicyanomethylene (DCM) and pyranine (HPTS). These dyes exhibit broad emission bands that cover a

• -emitting diode (LED); pyranine; zinc hydroxyacetate; Introduction Light-emitting diode (LED) devices are the most developed lighting systems today. 95% of LEDs found on the market generate white light by combining the blue light of a semiconductor diode (GaN or InGaN) with the broad yellow emission of the

• organic dyes that meet these criteria, there are xanthene derivatives (fluorescein, rhodamine), acriflavines, arylsulfonates, cyanines and pyrans. Only a few organic dyes can be excited by a blue LED emission centred at 450 nm. Among these dyes, mention can be made of dicyanomethylene and pyranine (Figure
