CsPbBr_3–zI_z/Y(X) nanocomposites based on FAU (Y and X) zeolites and halide perovskite nanoparticles (HP NP) with CsPbBr_3–zI_z composition (z = 0 or 1.8) are prepared. The dependence of HP NP content on the SiO₂:Al₃O₂ ratio in the parent zeolite and the formation of composite nanorods regardless of zeolite type in the case of iodine-containing HP due to the directional growth of CsPbBr_1.2I_1.8 crystals towards the (110) plane are shown. It is found that CsPbBr_3–zI_z/Y(X) materials are characterized by a significantly greater lifetime and intensity of photoluminescence in comparison with individual HP due to confinement effect. Highly stable films of CsPbBr_3–zI_z/Y(X)@Sil (z = 0 or 1.8) nanocomposites in silicone, which are characterized by a significant reduction of the luminescence band width, which is associated with the effect of silicone polymer on halide-ion exchange in HP, are prepared. It is shown that the color rendering index could be increased up to 95, while the partial index R₉ could be increased up to 99 at correlated color temperature of ~4500 K when using CsPbBr_1.2I_1.8/X@Sil in white light emitting diodes.
