 Abstract: This chapter discusses potential microlasers based on aluminium phosphate (AlPO4)-5/4-dicyanomethylene-2-methyl-6-p-dimethylaminostyryl-4H-pyran (DCM) composites. Through in situ inclusion, perfect hexagonal grown AlPO4-5 crystals are loaded with the laser dye DCM. The highest dye concentration is located in the middle of the crystals decreasing to the ends, showing that the dye is included in the early times of crystals growth. As DCM exceeds the pore diameter of AlPO4-5, mesopores are induced during incorporation. Spectroscopic investigations prove the alignment of the dye molecules within the one-dimensional channel system of the AFI structure. DCM also undergoes trans–cis photoisomerization. As spectra of DCM in A1PO4-5 indicate the presence of another absorbing species, it is suggested that a mixture of trans and cis DCM is present in the pores.
