Abstract

A white fluorescent lamp is prepared with a substrate and a high voltage circuit. The substrate has a fluorescent layer with silicon quantum dots. The lamp generates a white light by exciting the substrate with the circuit through a spark gap. A photoelectronic conversion is improved and a cost is lowered by using a cheap material as silicon.
