Abstract
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.
Claims18
A light source having a broad, continuous emission wavelength of from about 435 nm up to 1600 nm and higher, comprised of a mixture of inorganic phosphors activated with copper or silver and co-activated with a halide or a trivalent ion when excited by a source of light energy.
A light source having a broad, continuous emission wavelength of from about 435 nm up to 1600 nm and higher, comprised of a mixture of II-VI phosphors activated with copper or silver and co-activated with a halide or a trivalent ion when excited by electron bombardment.
A phosphor mixture comprising phosphors having an emission frequency varying from about 600 to about 1600 nm.
