Abstract : The aim of this study was to design a device for
explosives detection. The study design is based on
excited steady-state luminescence quenching
registration. Sensor’s material luminescence
intensity reduction occurs due to an interaction of
explosives vapours contained in the air. The
decrease rate of the luminescence intensity
indicates the concentration of vapours. To study
the luminescent properties of the sensor element,
its luminescence spectra excited by photons with
energies in the range 280 - 425 nm were measured.
The excitation photoluminescence spectra for
luminescence bands of the sensor element were
also measured. Excitation source was light
emitting diode (375 nm) and luminescent signal
receiver was a photodiode (430 - 650 nm) in device
designed. The device is operated under control of
a program. The algorithm provides multiple
operating modes (configuration, calibration,
measurement etc.). Thus this device is referred to
the class of devices with increased sensitivity to the
explosives vapors. The advantages of device are
autonomic power, small weight and sizes,
simplicity of device operation for measurements.
