“…The films prepared by PLD technique exhibit sharp step of index of refraction between the substrate and the film [15] and, as we have proved, a better adhesion than the thermally evaporated films (higher energy of vapor 'molecules' or evaporated fragments). Better adhesion was found for all films prepared in our laboratory [11][12][13][14]28,111] and also by others. The density of deposited films is often higher due to higher kinetic energy of vapor particles.…”

“…9, [13]) probably again as a consequence of densification of PLD films due to increasing kinetic energy of plasmaplume particles. In TE films, the changes of index of refraction after exposure and/or annealing are analogous as in TE films of As-S system [111], i.e. index of refraction increases with exposure and even more with annealing.…”

“…These glasses are lowphonon energy materials and are generally transparent from the visible to infrared. [1][2][3][4] Their usage ranging from optics, electronics to memory applications has stimulated a wide interest for a more thorough understanding of such materials properties and the variations of such properties with composition. [5][6][7][8][9][10][11] As for As 40 S 60 , it has stability in structure and its chemical property due to its average coordination number (∼2.4), which closes to the critical coordination number.…”

Effect of compressedon the size and stability of reverse micelles: Small-angle x-ray scattering and phase behavior study The Journal of Chemical Physics 118, 3329 (2003) The recovery response characteristics of optical stopping effect on the low-impurity As 20 S 80 system (P 2 As 20 S 78 and Sn 1 As 20 S 79 ) film waveguides are investigated in detail. Compared with As 20 S 80 , P 2 As 20 S 78 film waveguide deteriorates the response behavior of recovery propagation and is mainly characterized by the slow recovery propagation process with the disappearance of the fast rising edge. On the contrary, Sn 1 As 20 S 79 can improve evidently the earlier recovery stage by shortening response time of the rising edge to the milliseconds level, and also reduce the optical propagation loss. Experiments also show that the optical stopping effect can reach a saturated degree under He-Cd laser illumination for no less than 800 ms, and the addition of an assistant He-Ne laser may improve the recovery response slightly but not significantly.

In this study, undoped and cobalt‐doped manganese oxide Co:Mn3O4 (0, 2, and 4 at%) are elaborated by the spray pyrolysis procedure on glass substrates. The effect of cobalt doping concentrations on the structural, morphological, and optical features (linear and nonlinear) are investigated through the X‐ray diffractometer, Raman spectroscopy, Scanning Electron Microscopy with an attached energy dispersive X‐ray and UV–Vis‐NIR spectrophotometer. The XRD investigations exhibit a polycrystalline tetragonal structure for all Co:Mn3O4 and confirm by Raman results with the distinctive tetragonal mode A1g at 657 cm−1. The SEM images show an increase in roughness as cobalt doping concentration increases. The EDS quantitative analysis revealed the presence of manganese, oxygen, and cobalt. Furthermore, the optical investigation is pursued firstly through the linear optical that showed a decrease in the transmittance, and optical band gap energy as the cobalt concentration increased due to oxygen vacancies and defects and the increase of refractive index from 2.05 to 2.21. Second, the nonlinear optical parameters show a high value of the nonlinear refractive index 3.75 × 10−7 (esu) and the third‐order susceptibility χ3 = 2.2 × 10−8(esu) of Co:Mn3O4(2at%). These values put the Co:Mn3O4(2at%) thin layer as a candidate in the optoelectronic applications as a third‐order nonlinear medium.
