The invention provides an optoelectronic device comprising a porous material and a material with perovskite crystal structure in contact with the porous material. The porous material is further characterised in that the pores present a well defined average size, in the range of 1-100nm, and characterised in that it is an ordered network which shows a periodicity in one, two or three spatial directions. The perovskite material is infiltrated within the porous material, resulting in a mesostructured and ordered perovskite material. This spatially confined perovskite shows a luminescent emission whose range of wavelengths can be modified changing the pore size of the mesostructure. This invention solves the problem of tuning the emission of perovskite materials without varying their composition. The invention can be used as both light emitting and photovoltaic devices.
