Opis:: Pulsed laser ablation in ethanol at room temperature with laser fluence 4.62 J/cm2 was employed to synthesize pure zinc oxide (ZnO) and Er- doped ZnO nanocolloidal suspension. The structural properties were determined by using x-ray diffraction (XRD) method and was confirmed its hexagonal wurtzite structure. The photoluminescence spectra (PL), AFM and FTIR measurement of the synthesized pure and Er-doped ZnO is carried out. The photoluminescence spectra measurements show that all the samples have ultraviolet emission and green emission and the surface granular morphology. The FTIR spectra indicate the existence of Zn-O, Er-O-Er and Er-O stretching modes. Al/ZnO/P-Si/Al and Al/Er-ZnO/P-Si/Al photodetectors hetrojunction has two peaks of response located at 650 nm for and 790 nm and the first peak shifted to 550nm for the doped hetrojunction with max sensitivity 0.7A/W. The maximum specific detectivity is 4.3×1012 W-1•cm•Hz-1 and 3×1012 W-1 •cm•Hz-1 for undoped and doped hetrojunctions respectively. The values of the built-in potentials 0.9 volt for Al/ZnO/P-Si/Al heterojunction and 0.6 volt for Al/Er-ZnO/P-Si/Al hetrojunction.
