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
