Application: | DCM can be used as a laser dye to enhance the emission of distributed feedback (DFB) device by FÖrster resonance energy transfer (FRET). It may be used as a capping layer that allows the conversion of blue to red colored emission in organic light emitting diodes (OLED). DCM may also find potential applications in the enhancement of energy transfer of different devices like metal organic frameworks (MOFs), dye sensitized solar cells (DSSCs) and polarity sensors. |
Features and Benefits: | Voltage-tunable multicolor emission with enhanced luminance (~1000 cd/m2) was observed using varying amounts of DCM dye in a polymer light-emitting diode (PLED). |
