Spinel ferrite based nanoparticle material has been at the forefront of contemporary nanotechnology for use in various industrial and biomedical applications. The preparation and characterization of zinc ferrite nanoparticles (ZFNPs) doped with polyvinyl alcohol (PVA) are reported in this work. The formulated ZFNP/PVAs were characterized using powder X-ray diffraction (XRD), scanning electron microscopy (SEM), UV-visible spectroscopy, photoluminescence (PL) and a vibrating sample magnetometer (VSM). The XRD established the cubic spinel crystal structure of the as-prepared and calcined sample with an increase in the crystallite size after the calcination. The SEM analysis showed a spherical morphology within the range of 10-40 nm after calcination. The bandgap energy was enhanced after calcination. The PL analysis revealed a prominent peak in the UV band, which showed the characteristics of the formulated nanostructure. Transformation to a superparamagnetic nature was observed after calcination. It is noteworthy that after calcination of the formulated ZFNP/PVAs, the structural, optical, bandgap energy, morphology, photoluminescence and the magnetic properties were influenced and enhanced for various applications, chiefly for hyperthermia, magnetic resonance imaging, drug delivery and allied disciplines.

尖晶石铁氧体基纳米颗粒材料一直在当代纳米技术的最前沿，可用于各种工业和生物医学应用。这项工作报道了掺杂聚乙烯醇（PVA）的铁酸锌纳米颗粒（ZFNPs）的制备和表征。使用粉末X射线衍射（XRD），扫描电子显微镜（SEM），紫外可见光谱，光致发光（PL）和振动样品磁力计（VSM）对配制的ZFNP / PVA进行表征。XRD建立了所制备和煅烧样品的立方尖晶石晶体结构，煅烧后微晶尺寸增加。SEM分析显示煅烧后在10-40nm范围内的球形形态。煅烧后带隙能量增加。PL分析显示紫外线带中有一个突出的峰，这表明了所配制纳米结构的特征。煅烧后观察到转变成超顺磁性。值得注意的是，在煅烧所配制的ZFNP / PVAs之后，结构，光能，带隙能，形态，光致发光和磁性能在各种应用中受到影响和增强，主要用于热疗，磁共振成像，药物递送和相关学科。
