In this study, pristine and Nd-doped Fe₂O₃ NPs (NPs) were synthesized using precipitation method. After evaluation of sensing, the material become promising candidate to humidity detection. At room temperature, the Nd-doped Fe₂O₃ sensor demonstrated a better sensitivity and response time i.e. 70.74% and 32 s to 100% relative humidity (RH), over pristine sensor which showed sensitivity and response time values of 56.95% and 89 s, respectively, to the same RH value. Furthermore, the Nd-doped sensor revealed a negligible decrease in its sensitivity even after several weeks, suggesting high physiochemical stability and environmental robustness.

在本研究中，使用沉淀法合成了原始和 Nd 掺杂的 Fe ₂ O ₃ NPs (NPs)。经过传感评估，该材料成为湿度检测的有希望的候选材料。在室温下，Nd 掺杂的 Fe ₂ O ₃传感器表现出更好的灵敏度和响应时间，即 70.74% 和 32 s 到 100% 相对湿度 (RH)，超过原始传感器的灵敏度和响应时间值分别为 56.95% 和 89 s，分别为相同的 RH 值。此外，即使在几周后，掺 Nd 传感器的灵敏度也几乎没有下降，这表明其具有较高的物理化学稳定性和环境稳定性。
