A new ion source for ion mobility spectrometry based on UV laser action upon the surface of porous silicon, is described for the first time. It is found that the yield of TNT negative ions from this source is higher by an order of magnitude than in t

The efficiency of a YAG:Nd3+laser (λ = 1064 nm) and a diode continuous laser (λ = 440 nm) to initiate laser desorption of traces of trinitrotoluene (TNT) and cyclotrimethylenetrinitramine (RDX) is quantitatively compared with use of mass spectromet

Radiationless resonant electronic excitation transfer from silicon nanocrystals to I 2 molecules sorbed in pores of porous silicon was observed. Energy distribution of desorbed I 2 molecules was investigated by the time-of-flight mass-spectrometry te

Resonant radiationless electronic excitation transfer to I2 molecules sorbed in pores of porous silicon was observed. The mass-spectrometry technique was used to show that iodine excitation through the resonant transfer results in the desorption of s
