Ni doped ZnSe nanospheres in presence of PVA have been synthesized via a cost effective and simple solvothermal method. The structural and rnorphological characterization of as undoped and doped samples have been made using X-ray diffraction (XRD) and FESEM imaging techniques and it reveals the formation of Ni doped ZnSe nanospheres with crystallite size 6 nm. The observed red shift in absorption edge of Ni doped ZnSe as compared to undoped sample also indicates the formation of nanospheres. The PL spectra of Ni doped sample shows red shift with enhanced intensity. The molecular vibrations of PVA capped Ni doped ZnSe nanospheres have been studied and four new vibrational modes have been observed and reported.

通过一种经济有效且简单的溶剂热法合成了在PVA存在下掺Ni的ZnSe纳米球。使用X射线衍射（XRD）和FESEM成像技术对未掺杂和掺杂的样品进行了结构和形貌表征，揭示了形成了6 nm晶粒的Ni掺杂ZnSe纳米球的形成。与未掺杂的样品相比，观察到的镍掺杂的ZnSe吸收边缘的红移也表明了纳米球的形成。Ni掺杂样品的PL光谱显示红移强度增强。研究了PVA包覆的Ni掺杂ZnSe纳米球的分子振动，并观察和报道了四种新的振动模式。
