研究目的
To study the precipitation and generation of AgNPs within the borate glasses by 1064 nm Nd:YAG laser irradiation for borate glasses doped by AgNO3 and to study the dielectric properties of the precipitated borate glass samples as a function of frequency at different temperatures.
研究成果
The precipitation of AgNPs inside the borate glass matrix was successfully performed by 1064 nm Nd:YAG laser pulses. The presence of AgNPs was confirmed by XRD, UV/Vis., HR-TEM, and FE-SEM analyses. The dielectric properties of the glass samples were found to be temperature and frequency dependent.
研究不足
The study focuses on the precipitation of AgNPs in borate glasses using a specific laser wavelength and parameters. The effects of varying laser parameters or using different glass matrices were not explored.
1：Experimental Design and Method Selection:
Borate glasses doped with silver nitrate were synthesized via the melt annealing technique and irradiated by a 1064 nm Nd:YAG laser to precipitate silver nanoparticles.
