Solid phase luminescence determination of aluminum using UV laser and optical multichannel spectra analyser (OMA) was descnbed Silica (SG) modified sith ion associate high molecular eiglu quatemar ammornurn salt (QAS) lumogallion (LG) was used as active sensor element Photoluimnescence (PL) of the modified sorbent as excited b) pulse N2 laser and then studied by OMA using CCD camera for detection of the pulse PL spectra and IBM PC for analyses It was shown that
the intensity of PL pulse peaks of the modified SG noticeabl increased ith the nsing of Al (III) concentration in the range
of 1 10-6 ÷ 1 10-4M. The detection limit of Al as 1 10-7 mole/1 at sample volume 50 ml and mass of the sorbent 0.05 g. PL spectra of Al-LG complex formed on the surface is consisted of two bonds Their possible reasons are discussed The developed method can be successfully used for working out optical sensor for aluminum determination in the environment.
The possibilities of the laser-thermal diagnostics of the hidden defects in the solid state materials and multilayer structures are reported. The approach is based on the spectral analysis of the thermal radiation flux induced by the high power pulsed laser-surface interaction. To prove the method, the next things have been studied: (1) the distribution of the temperature and thermal radiation fields in the metal and semiconductor structures that is heated by the pulsed laser radiation under various laser regimes and material parameters; (2) the kinetics of surface and interface charge carriers recombination in the multilayer structures; (3) the thermal emission of the inherent radiation of multilayer structures that determines their basic characteristics: sizes of the macrodefects, thickness of interlayers, depth of penetration, thermal and electric conductivity, rate of heating and cooling of the local areas under the laser beam spot. It was found that even small variation in conditions of the laser-surface interaction due to the metal and dielectric defects and heterogeneity in the material structure can produce large changes in the amplitude and spectra of the laser induced thermal radiation, so such a technique could serve as a powerful tool for noninvasive inspection and express control of the hidden topology in the material structure, and the velocity of the surface carriers recombination of semiconductors can be monitored and controlled well.

To state more precisely our knowledge of the vibrational energy transfer with Cl2 molecules in active media of the gas flow and chemical lasers, the study of nonequilibrium vibrational relaxation of the thermally heated and partially dissociated molecular chlorine in the supersonic flow is carry out. An experimental technique, based on the sensitive spectroscopic diagnostics and numerical gasdynamic and kinetical modeling is used. The parameters of vibrational kinetics of the molecular chlorine is found. The effect of chemically active Cl atoms on the rate of V-T deactivation of Cl2 molecules is determined.
Based on the measurements of the absolute emissivity of the thermally heated molecular chlorine in the shock wave flow, the redetermination of radiative characteristics of the Cl2 B3(Pi) o+u yields X1(Sigma) +g and A1(Pi) 1u yields X1(Sigma) +g electronic transitions was made with the aim of pre-laser studying a potential new laser active media. Reasons for errors in previous works are discussed.
