In the current study, the structural, optical, and magnetic characteristics of Fe-doped ZnP nanoparticles prepared by the solid-state reaction technique with various concentrations of Fe (x = 0.00, 0.02, 0.04, 0.06, and 0.08) were investigated. Studies using X-ray diffraction (XRD) verified that all of the produced samples had a tetragonal structure without any other phase, and that the lattice parameters increased (a = 8.090 Å, c = 11.421 Å to a = 8.120 Å, c = 11.499 Å) as the amount of dopant increased. The scanning electron microscopy (SEM) performed on the sample demonstrates that the grain size is almost spherical. The size of agglomerations slightly increases with increasing dopant concentration. The results of an energy dispersive X-ray analysis (EDAX) are almost exactly what was anticipated for the atomic weight ratios. The optical bandgap of the samples went from being 1.406 eV to being 1.453 eV when the dopant concentration was raised. When excited at wavelengths of 210 nm and 240 nm, rather than 307 nm, very intensity Photoluminescence (PL) emission spectra were detected in all of the samples. Vibrating sample magnetometer (VSM) verified that magnetic moment is found to increase (0.08829 emu/g to 0.23125 emu/g) with increase of dopant concentration from 0.02 to 0.08.

未掺杂和 Fe 掺杂 Zn3P2 纳米粒子的室温铁磁性：结构、光学和磁性

在当前的研究中，研究了通过固相反应技术制备的不同Fe浓度（x = 0.00、0.02、0.04、0.06和0.08）的Fe掺杂ZnP纳米粒子的结构、光学和磁特性。使用 X 射线衍射 (XRD) 的研究证实，所有生产的样品都具有四方结构，没有任何其他相，并且晶格参数增加（a = 8.090 Å，c = 11.421 Å 至 a = 8.120 Å，c = 11.499 Å)随着掺杂剂数量的增加。对样品进行的扫描电子显微镜（SEM）显示晶粒尺寸几乎为球形。随着掺杂剂浓度的增加，团聚体的尺寸略有增加。能量色散 X 射线分析 (EDAX) 的结果几乎与原子量比的预期完全一致。当掺杂剂浓度增加时，样品的光学带隙从1.406 eV变为1.453 eV。当在 210 nm 和 240 nm（而不是 307 nm）波长下激发时，在所有样品中均检测到非常强度的光致发光 (PL) 发射光谱。振动样品磁力计（VSM）验证发现，随着掺杂剂浓度从0.02增加到0.08，磁矩增加（0.08829 emu/g到0.23125 emu/g）。
