Abstract: We present results of studying the luminescent characteristics of optical fibers with CdS and CdSSe quantum dots (QDs) for spark detectors with up-conversion of the spark flashing spectrum to the long-wavelength range. It is shown that, by selecting a proper QD composition and size, it is possible to shift the luminescence band position toward the region of maximum sensitivity of a Si photodetector.
