Organic-inorganic hybrid perovskite is an important photoelectric material，which is widely used in photovoltaic devices. And their stability will significantly improve when sample limited in MOFs，however，the effect of limitation on its photodetector performance is still under investigation. In this study，MAPbBr3 were limited in ZIF-67，a typical MOFs material，and by adjusting the amount of ZIF-67， MAPbBr3@ZIF-67 with different concentrations ZIF-67 was formed. It was found that the addition of ZIF-67 did not affect the lattice structure and absorption edge position of MAPbBr3，but could improve its crystallinity. In addition，since ZIF-67 still has significant absorption at wavelengths longer than 550 nm，the composite also shows significant absorption characteristics in this wavelength range. When the synthesized sample used in photodetector，the corresponding switching ratio of the device is improved more than an order of magnitude. This study provides a new idea for further improving the response performance of the device.
