Witryna16 sie 2013 · This work reports the enhanced emission at 2.7 µm in Er3+/Ho3+-codoped fluorotellurite glass upon a conventional 980 nm laser diode. The significantly reduced green upconversion and 1.5 µm emission intensity in Er3+/Ho3+-codoped samples are observed. The results suggest that the Er3+: 4I13/2 state can be efficiently … WitrynaAn organic/inorganic hybrid up-conversion device was demonstrated in this work, which can convert near-infrared light (NIR) to visible green at high conversion efficiency. The upconverter was fabricated by integrating an In0.12Ga0.88As/GaAs multiquantum wells (MQWs) photodetector (PD) with an organic light emitting diode (OLED). The …
