FLUORESCENCE-REDDENING MEMBRANE AND RED-EMITTING DEVICE |
摘要 |
<p>The present invention relates to a fluorescence-reddening membrane which comprises a light-transmittable medium and, dispersed therein, (a) a rhodamine base fluorescence pigment and (b) a fluorescence pigment which has absorptions in the blue region and induces energy transfer to and reabsorptions from the rhodamine base fluorescence pigment. According to the present invention, it is made possible to provide the fluorescence-reddening membrane capable of converting the color of light emitted by a blue-emitting organic electroluminescence device to a red light at a high conversion efficiency and also to provide an inexpensive red-emitting device capable of reducing the size and thickness of itself. <IMAGE></p> |
