Abstract: We introduce a groundbreaking multifunctional platform predicated on 5CB (4-cyano-4’-pentylbiphenyl) liquid crystals infused with Dysprosium-doped Lithium zinc phosphate phosphor nanoparticles [Li4Zn(PO4)2: Dy3+] (DLZP-NPs), which demonstrate adjustable characteristics suitable for microwave and optical applications. The incorporation of phosphor nanoparticles into 4-cyano-4’-pentylbiphenyl (5CB) liquid crystals has been empirically demonstrated to significantly augment both optical and microwave properties, rendering them exceptional candidates for advanced technological applications. Polarized optical microscopy (POM) elucidates a homogenous director orientation, whereas UV-V is spectroscopy indicates a reduction in energy bandgap from 3.96 eV to 3.86 eV, signifying enhanced optical characteristics. Significantly, the S11 (reflection coefficient) parameter illustrates an increase in resonance frequency from 12.3 GHz to 14.4 GHz, subsequently followed by a decrease to 8.59 GHz, thereby illustrating a modifiable microwave response. This pioneering platform affords a distinctive amalgamation of optical and microwave properties, establishing it as a highly attractive candidate for applications in tunable filters, antennas, and optical communication systems.
