Abstract |
|
|
| CdSe is a II-VI group material which has various applications in different areas of physics, such as display devices, solar cells, photodetectors, electro photography and lasers. The pure and different volumes of neodymium (Nd) doped CdSe thin films are prepared onto glass slides by chemical bath deposition method. The structural property shows the cubic structure of pure and Nd doped prepared thin film materials and the average crystal sizes 22.61 and 15.82nm for pure and Nd doped CdSe materials respectively. The optical bandgap energy were obtained in the range 1.98 and 2.02eV for pure and different volumes of Nd doped CdSe films. The electrical property shows the semiconducting behavior of the films. The samples also give increased dark current in the presence of neodymium. The absorption spectra exhibit the absorption of solar spectra in the visible range.
