Abstract Blue-green electroluminescence has been observed in free-standing diamond films which were deposited by microwave plasma assisted CVD on silicon substrates. The electroluminescence device is driven by a 60 Hz power supply. The threshold voltage was about 112 V peak-to-peak. The electroluminescence spectrum at room temperature, showed a blue-green band with the peak centered at 485nm suggesting band A type emission. Electroluminescence was also observed at 77K.
