Fiber-optic temperature sensor based on CdSe semiconductor nanocrystal doped glass

We propose a temperature fiber sensor based on CdSe-nanocrystal-doped phosphate glass. This glass demonstrates a reversible temperature-induced absorption edge shift at temperatures less than annealing temperature ofthe glass (<370°C). A sensor, tested in the temperature range of—20 to +120°C, is shown to exhibit a linear response to temperature variations.
