Pure alkali halide crystals are transparent throughout the visible region of the spectrum. The crystals

may be colored in a number of ways

(1) by the introduction of chemical impurities

(2) by introducing an excess of the metal ion

(3) by X-ray, g-ray, neutron and electron bombardment

(4) by electrolysis

Colour centres produced by irradiation with X-rays

When a X-ray quantum passes through an ionic crystal, it will usually give rise to a fast photo-electron with an energy of the same order as that of the incident quantum. Such electrons, because of their small mass, do not have sufficient momentum to displace ions and therefore loose their energy in

producing free electrons, holes, excitons and phonons. Evidently these while moving near the vacancies form trapped electrons as well as trapped holes. The trapped-electron or trapped-hole centres so formed can be destroyed (bleached) by illuminating the crystal with light of the appropriate wavelength or warming it.

Thermoluminescence

Important information about the colour centres can be obtained by measuring the changes that occur when a coloured crystal is gradually heated. As the temperature is raised electrons and holes escape from their

traps at an increasing rate. The freed charges can recombine with each other or with other defects and give out luminescence by recombination.

The resulting thermoluminescence or ‘glow’ reaches maximum and then decreases to zero as the supply of trapped electrons or holes becomes exhausted. The plot of luminescence intensity verses temperature, taken

at a constant heating rate, is called the ‘glow curve’. It may contain one or many glow peaks, depending upon whether there are one or several different kinds of traps.

From the glow curve one determine the trap depth; the deeper the trap, the higher the temperature of the glow peak. A correlation between the temperature at which thermoluminescence occurs and the temperature at which particular band bleach can give valuable information about specific

centres. Typical results obtained from this set-up for

KCl crystal are shown in figure.

The experiment consists of the following

These instruments are used in contact angle measurement, surface free energy analysis, and surface or interfacial tension measurement.The V TECH (VT) series contact angle meters have a range of systems starting from DMs-200, which is the basic model, to the most sophisticated VT-701.The VT-200 model is used to determine contact angle using the sessile drop method in static mode.

From model VT-CE1, all instruments can determine contact angle using the sessile drop method in static mode as well as in dynamic mode. The surface tension of a liquid sample can also be determined. The robust FAMACS software ensures that the system can also give dynamic contact sessile drop method,extension/contraction method, surface or interfacial tension of liquids with pendant drop method,sliding method, and dynamic sliding method. This is the most automatic model and even stage movement and droplet deposition can be controlled through the PC.

Optional accessories are numerous to choose from including computer-controlled dispenser, sliding method, temperature control of stage, temperature control of dispenser, and high speed camera.With the surface free energy software, the solid surface free energies and their components from the results of contact angle with different liquids can be measured.If surface free energy is the main analysis, then there is also an option called surface energy kit which consists of five kinds of probe liquids and proper needles.

Applications

The contact angle meter has application in the pharma field, where the wettability of powders can be studied. The contact angle measurement gives remarkable data on wettability and thus pharma companies can use this tool in their analytical research and development. It can also be used to analyze the processes of coating, cleaning, and surface finishing in research institutes.
