Scientists have discovered a potentially promising infrared LED and infrared detector component. This compound -- composed of calcium, silicon and oxygen -- is cheap to produce and non-toxic. Many of the existing infrared semiconductors contain toxic chemical elements, such as cadmium and tellurium. The new material may be used to develop less expensive and safer near-infrared semiconductors.
