Chapter 1 Applications of Luminescence to Fingerprints and Trace Explosives Detection
Fingerprints and trace explosives detection requires great sensitivity, which is provided by luminescence and appropriate physical and chemical treatments. Ninhydrin, 1,2-indanedione and other chemicals react with the amino acids present in the fingerprint residue. The chemically treated samples, on which the prints are to be detected, are excited with the blue lines 476.5 and 488 nm of an Argo...
متن کاملDIRECT LUMINESCENCE AND THERMALLY STIMULATED LUMINESCENCE OF 4H CdI2
Direct luminescence (DL) spectra of 4H Cd12 in the spectral region 1.8-3.4 eV at temperatures between 9.3 and 215 K and thermally stimulated luminescence (TSL) spectra are reported. The DL spectra consist of several overlapping broad emission bands. These bands are due to radiative recombination of localized (trapped) electrons with localized (trapped) holes. With a simple theory, which takes i...
متن کاملIncomplete Trace Data and Trace Driven Simulation
| We illustrate the sensitivity of trace driven simulation results to the completeness of the input trace data. This is done by comparing cache simulation results obtained using traces similar to many found in the published literature with those obtained using a hardware monitor which we have developed. Cache miss rates from single process traces without operating system references are shown to...
متن کاملTsallis distribution and luminescence decays
Usually, the Kohlrausch (stretched exponential) function is employed to fit the luminescence decays. In this work we propose to use the Tsallis distribution as an alternative to describe them. We show that the curves of the luminescence decay obtained from the Tsallis distribution are close to those ones obtained from the stretched exponential. Further, we show that our result can fit well the ...
متن کاملLuminescence and energy transfer in
Lu3Al5O12 (LuAG) doped with Ce 3+ is a promising scintillator material with a high density and a fast response time. The light output under x-ray or γ-ray excitation is however well below the theoretical limit. In this paper the influence of co-doping with Tb is investigated with the aim to increase the light output. For singly doped LuAG (with Ce or Tb) high resolution spectra are reported giv...
