Intense organic neodymium emission with narrow line width and near-infrared emission equivalent in intensity to organic semiconductor emitting material is achieved through efficient sensitization effect from a composite organic sensitizer. The performance is optimized at high concentrations of Nd3+ ions, providing a quantum efficiency of about 40%. The material system is suitable for thin films compatible with integrated optics applications.
Intense organic neodymium (Nd3+) emission is obtained with near-infrared (NIR) emission equivalent in intensity to that of an organic semiconductor emitting material. The advantage of Nd3+ emission is its narrow line width and NIR emission, which is enhanced by similar to 3000 times at low excitation power through an efficient sensitization effect from a composite organic sensitizer. This performance is optimized at high concentrations of Nd3+ ions, and the organic perfluorinated system provides the ion excitations with a quantum efficiency of similar to 40%. The material system is applicable to thin films that are compatible with integrated optics applications.
