A method for efficient plasma etching of surfaces inside three-dimensional structures can include positioning an inner electrode within the chamber cavity; evacuating the chamber cavity; adding a first inert gas to the chamber cavity; regulating the pressure in the chamber; generating a plasma sheath along the inner wall of the chamber cavity; adjusting a positive D.C. bias on the inner electrode to establish an effective plasma sheath voltage; adding a first electronegative gas to the chamber cavity; optionally readjusting the positive D.C. bias on the inner electrode reestablish the effective plasma sheath voltage at the chamber cavity; etching the inner wall of the chamber cavity; and polishing the inner wall to a desired surface roughness.

A high pressure lamp bulb adapted to simultaneously emit distinct emission spectra of a desired wavelength, the lamp bulb comprising an envelope for containing a fill material under pressure and a fill material, the fill material including a material capable of forming at least two dissimilar excimer species in an amount to provide a total fill pressure no less than about 750 Torr at room temperature.

A method of tagging and detecting objects is disclosed which comprises the steps of: (a) applying a volatile taggant to the object; and (b) subsequently detecting the presence of the taggant by the absorption, transmittance, reflectance, photon emission or fluorescence of the taggant and therefore a proximity of the tagged object. The present invention therefore provides optical sensing means which do not require physical separation of differing compounds for discrimination thereof.
