研究目的
Investigating the growth of pure and BFO doped KCl crystals by Czochralski technique and their application in fabricating microstrip patch antenna for GHz applications.
研究成果
BFO doping in KCl single crystals improves optical transparency, mechanical hardness, and dielectric properties, making them suitable for applications in GHz frequency microstrip patch antennas. The resonant frequency of the antenna can be tuned by BFO doping, demonstrating the potential of these materials in electronic communication devices.
研究不足
The study focuses on a specific doping concentration of BFO (0.1 mol%) in KCl crystals. The effects of varying doping concentrations and other dopants were not explored. The application is limited to GHz frequency range for microstrip patch antennas.
1：Experimental Design and Method Selection:
The study involved the growth of pure and BFO doped KCl single crystals using the Czochralski technique. Structural, chemical, and electrical properties were characterized by XRD, EDX, and dielectric studies, respectively. Photoluminescence (PL) was used for optical characterization.
2：Sample Selection and Data Sources:
Highly pure powders of Bi(NO3)2·5H2O, Fe(NO3)3·9H2O were used for BFO synthesis. KCl single crystals were grown with and without BFO doping.
3：List of Experimental Equipment and Materials:
Powder XRD, single crystal XRD, EDX, PL spectrometer, Vicker’s microhardness tester, and equipment for dielectric measurements.
4：Experimental Procedures and Operational Workflow:
The crystals were grown, characterized, and then used to fabricate microstrip patch antennas. The performance of these antennas was evaluated.
5：Data Analysis Methods:
Data from XRD, EDX, PL, microhardness tests, and dielectric measurements were analyzed to understand the effects of BFO doping on KCl crystals.
