LIGHT SOURCES HAVING A CONTINUOUS BROAD EMISSION WAVELENGTH AND PHOSPHOR COMPOSITIONS USEFUL THEREFOR

摘要

Phosphor mixtures having a continuous emission wavelength of from about 400 to about 1500 nanometers and higher can be made from inorganic phosphors. Such phosphor mixtures can be used as light sources together with light sources or electron beam generators to provide a broad range of emission wavelength. Such phosphors can also be used to determine blood sugar levels in a human by emitting the phosphor light onto a light transmissive portion of the body, such as an ear lobe, and measuring glucose levels.
