The optical spectrum of the emitted light consistently

• is formed by application of the electrical bias, giving rise to light emission via atomic transitions in gaseous zinc and oxygen. The broad spectrum, white light emission is possibly due to the free electron transitions in the plasma and blackbody radiation from molten silicon. The white light may

The broad spectrum (white light) emission (Figure 5 and Figure 6) can be ascribed to the free–free electron transitions in
