Abstract:
Measurement of the intrinsic properties of processing plasmas is critically important in understanding discharges so that the optimum conditions can be achieved. Several different diagnostic methods have been developed and tested. A planar probe has been used to measure the ion flux and electron temperature in both inductively coupled and capacitively coupled plasma systems, at various pressures and applied powers, using the assumption that the electron energy distribution is a Maxwellian.</p> Frequency modulation spectroscopy (FMS) has been used to detect species in a plasma.

Extensive information can be obtained on wave-particle interactions and wave fields by direct measurement of perturbed ion distribution functions using laser-induced fluorescence (LIF).

If the laser intensity is increased to obtain a better LIF signal, then optical pumping can produce systematic effects depending on the collision rates which contr

In 2005, our group first reported a two-pulse multi-element analysis technique that was both sensitive and minimally destructive. The first laser pulse ablated a thin layer of the sample over a hundred m spot; the second laser pulse at 193 nm induced multi-analytes in the desorbed plume to fluoresce. Since then, this technique of laser-excited atomic fluorescence (LEAF) of ablated plumes, or PLEAF for short, had been applied to the analysis of aqueous lead colloids and metals. Sub ng/g and tens of atto-mole detection limits were demonstrated. The non-selective photoexcitation in PLEAF was beli

The Langmuir – Blodgett (LB) method is one of the useful techniques to prepare ultra-thin films with precise organization of embedded dye cations.

In our study we used laser dye cation (rhodamine) with long alkyl chain in the structure, which makes this cation sufficiently hydrophobic.
