Eu doped porous nanostructured SrTiO films and powder fabricated by sol-gel route without using any precursor template are characterized by different morphology and phase composition. The films show red and yellow luminescence with the most intensive photoluminescence (PL) bands at 612 nm and 588 nm, respectively. Raman, secondary ion mass spectrometry (SIMS), and X-ray diffraction (XRD) analysis of undoped nanostructured porous SrTiO films showed the presence of TiO, SrO, and SrTiO phases and their components. The undoped porous SrTiO films are photosensitive and demonstrate resistive switching. The capacitance-voltage hysteresis loops with the width of about 6 V in the frequency range of 2 kHz-2 MHz were observed.
通过溶胶 - 凝胶法制备的、不使用任何前驱体模板的铕掺杂多孔纳米结构SrTiO薄膜和粉末，具有不同的形貌和相组成。这些薄膜呈现出红色和黄色发光，最强的光致发光（PL）带分别位于612nm和588nm处。对未掺杂的纳米结构多孔SrTiO薄膜进行拉曼光谱、二次离子质谱（SIMS）和X射线衍射（XRD）分析，结果表明存在TiO、SrO和SrTiO相及其组分。未掺杂的多孔SrTiO薄膜具有光敏性，并表现出电阻开关特性。在2kHz - 2MHz频率范围内观察到宽度约为6V的电容 - 电压滞后回线。
