    • The present invention is directed to a structure, having first areas consisting of or comprising a network of organic polymer material and second areas consisting of a nematic and/or smectic liquid crystal material, comprising at least one or more nematic and/or smectic liquid crystals and a photoluminescent material, wherein the first and second areas alternate in at least a first plane, while the composition of the film is substantially invariable in at least one direction which is angular to the said first plane, or second areas are completely surrounded by first areas, and the said areas are located in a periodic pattern, wherein the nematic and/or smectic liquid crystal material in the second areas extends in the longitudinal direction of the said areas from one end of the area to the other, the structure being arranged between two substrates, at least one of which is light transmitting. The structure together with the substrates may be a Bragg grating and can be used as a DFB laser. It can be prepared by providing a homogeneous and isotropic mixture including a photocurable monomer/oligomer, a nematic and/or smectic liquid crystal, and a photoluminescent material, filling said mixture into the space between two substrates and irradiating same with a light field such that areas of the mixture are irradiated while others are not. Under the irradiation, the mixture separates into areas comprising photocured polymer and areas consisting or comprising liquid crystals and photoluminescent material.
