NOVELTY - Hybrid photoactive material comprises at least one dye having fluorescent properties, which is an aromatic molecule or its resonant forms, where the dye being contained and encapsulated in a crystalline porous material with magnesioaluminophosphate (MgAPO) composition, characterized by having pores with a first diameter in the interval of 4-7 Angstrom , both limits included, and a second diameter in the interval of 4-7.5 Angstrom , both limits included, which has a one-way system of channels defined by rings of ten to twelve atoms of Al and P with tetrahedral coordination.    USE - The hybrid photoactive material is useful as a pigment, in paints, plastics, and ceramics; and useful in solid state laser, where the laser is integrated in a photonic device, where the photonic device is selected from solid state laser, an antenna device for activation of solar cells and a nonlinear optical device, where the non-linear optical device is selected from dichroic filters, frequency doublers and waveguide systems, and where laser is a solid state microlaser at one phenomenon selected from lasing reinforced by random scattering or laser (all claimed).    ADVANTAGE - Materials with improved fluorescence properties are provided.    DETAILED DESCRIPTION - Hybrid photoactive material comprises at least one dye having fluorescent properties and a structure of formula (I), which is an aromatic molecule and its resonant forms, where the dye being contained and encapsulated in a crystalline porous material with magnesioaluminophosphate (MgAPO) composition, characterized by having pores with a first diameter in the interval of 4-7 Angstrom , both limits included, and a second diameter in the interval of 4-7.5 Angstrom , both limits included, which has a one-way system of channels defined by rings of ten to twelve atoms of Al and P with tetrahedral coordination.    X=selected from CH or N;    Y=selected from S, O, N, CH and NH; such that when X=CH, Y' is selected from S, O, N, CH or NH, and when X=N, then Y'=0;    n=+1 when Y' equals s O, NH or S and n being equal to 0 when Y=N or CH;    R1, R2, R3 and R4=can be mutually identical or different and selected from H, CH3, CH2CH3 or N(R11)(R12); and    R11 and R12=mutually identical or different and selected from H, CH3 and CH2CH3.
