چکیده
This study reports on the synthesis and characterization of flexible nanocomposite films composed of potassium titanium phosphate (KTP) nanoparticles embedded in a polymer matrix. Structural analyses using X-ray diffraction (XRD) and Fourier-transform infrared (FT-IR) spectroscopy confirmed the successful formation of orthorhombic-phase KTP nanoparticles. The resulting nanocomposite films exhibited strong UV absorption around 280 nm, highlighting the effectiveness of KTP nanoparticles as UV absorbers for various optical and electronic applications. Photoluminescence (PL) studies revealed a sharp emission peak at approximately 550 nm with a narrow full width at half maximum (FWHM) of 30–40 nm, indicating high optical quality and minimal structural defects. The high emission intensity and estimated quantum yield of 50–70% demonstrate efficient energy transfer within the composite. The incorporation of KTP nanoparticles into the polymer matrix provided a stable and protective environment, enhancing optical efficiency to approximately 60–80% and reducing non-radiative losses. Morphological analysis showed the hydrothermally synthesized nanoparticles possessed rhombohedral to prismatic shapes with sizes of 1.5–2 μm. Mechanical testing indicated that the KTP/PMMA nanocomposite outperformed pure PMMA in both Young’s modulus and tensile strength, albeit with reduced elongation at break, reflecting increased stiffness. Overall, these results demonstrate the significant potential of KTP-polymer nanocomposite films for use in optoelectronic devices requiring high efficiency and stability.
