“…The obtained optical parameters are summarized in Table 1. These values agree with previously reported one, which varies between 1.9 and 2.2 eV, depends on the preparation techniques and crystalline structure and grain size of the α-Fe2O3 films [5,[15][16][17][18][19][20][21][22]34].…”

“…This behavior has not been reported elsewhere. The values and the behavior of the refractive index and the extinction coefficient (n and k) for the iron oxide thin films in the literature show a significant variation according to the elaboration techniques as well as the analytical methods used to extrapolate these parameters [5,15,18]. To corroborate the ellipsometric results, regarding the energy band gap, with which deduced from spectrophotometry measurements, using the value of SE k data the absorption coefficient α was calculated from the equation [27]:…”

“…Among indirect band oxide semiconductors the most known is TiO 2 (anatase). Some iron oxides can exhibit both direct and indirect bands [5,6]. Details about the spectroscopic features of TiO 2 (in dark or irradiated by electromagnetic radiation) are available in many publications [7,8].…”

A concise critical review of the antibacterial features of some nanoparticles (metallic and oxide semiconductors) is presented. The review starts with a brief analysis of the physical features of nanoparticles and includes a discussion about the system nanoparticles-water-light, which is of utmost importance in biological and medical cases. Both metal and semiconducting nanoparticles are releasing electrons under the effect of the incoming electromagnetic radiation (light). This is the source of major misunderstandings as the antibacterial features of nanoparticles can be intrinsic (in this case antibacterial capabilities will be measured in the absence of light) or mediated (in this case the antibacterial features will be observed solely under light irradiation). The critical review opens the discussion about the need for experimental measurements in dark and under the effect of light-a type of research that was typically disregarded. The main ideas are supported by examples from specialty research. New concepts as specificity and effectiveness of antibacterial features are tentatively suggested.

“…These oxide films are very useful material for the decision of problems of material science in the field of microelectronics and solar energy. For example, iron oxide thin films are suitable materials for photoelectrochemical solar cell for solar energy conversion, for microelectronic circuits as capacitors, for rechargeable batteries as negative electrode, for smart windows devices as electrochromic materials, for interference filters [8][9][10][11].…”
