Novel Method

Ferrography is a method for separating wear particles onto a slide. The method is based on the interaction between an external magnetic field and the magnetic moments of the particles suspended in a flow stream. It is advantageous in providing high detectability rate for a relatively large range of particle sizes (0.5–200 μm) [1]. A newer generation of ferrography, known as Bio-Ferrography, allows particles from five fluid samples to be isolated simultaneously on one slide and analyzed in terms of their number, chemistry, shape, dimensions, surface morphology, structure, etc. Since magnetization does not naturally occur in polymeric and biological materials, wear particles of such origins must be magnetized prior to Bio-Ferrography. This can be done, for instance, by binding to a ferromagnetic element, such as Er+3, originating from erbium chloride (ErCl3) solution. Such Bio-Ferrography technology has already been applied successfully in hip wear simulations for the separation of ultrahigh molecular weight polyethylene (UHWPE) wear debris suspended in bovine serum as lubricant [2].

We applied photoluminescence (PL) and photoacoustic techniques on erbium-doped porous silicon nanostructured ( Er -doped-PSN) to study the influences of weight percent (%) of erbium-doped in PSN. Erbium-doped PSN has been intensively studied due their potentiality for optical devices such as waveguide and optical amplifier. Electrochemical technique was used to prepare the PSN samples. Polished p-type [100] c- Si was used as based material. Erbium doping process was carried out by electrodeposition technique using Erbium Chloride ( ErCl 3) and ethanol composition as electrolyte. The weight percent of Er concentration is varied to get the optimum effect on PL. The doping process improves PL intensity and changing in peak position. Photoluminescence measurements were performed in the visible light range and excited with the 380 nm line a Xenon ( Xe ) light source. Photoacoustic (PA) measurements is useful to obtain the optical absorption characteristic for strongly scattering media such as PSN and it helps to confirm the possibility of a strong quantum confinement effect.
