چکیده
|
In the present work, we establish that ag-doped mesoporous bioactive glass (mbg) can be prepared by spray pyrolysis (sp) process. this process offers the feature of low processing times and continuous production. this work was prepared in two steps, the first step was to prepare the material (mbg), and the second step was to make a nano-layer of silver material on the surface of the (mbg) according to the time interval between two spray processes (2, 4, and 6 min). using scanning electron microscopy (sem), energy dispersive x-ray analysis (edx), uv-vis spectroscopy, and fourier transform infrared spectroscopy (ftir) were used to analyze the sample. according to the sem and edx analysis result, the suitable formulation of the precursors can be used to control the distribution of the ag dopant nanoparticles within mbgs. also, uv-vis shows that the absorption coefficient as a function of hυ (ev) and the extinction coefficient as a function of λ take the same behavior.
