摘要
通过与氧化锌的比较,我们在此报告基于 PrBa2Cu3-3xAl3xOy (AlPr:123)化合物(0.00 ≤ x ≤ 1.00)的光学和光致发光(PL)分析方面对 n 型半导体的研究。x ≤ 0.30 的样品为四方结构,x > 0.30 时变为正方结构,而 ZnO 则为钨锆石(六方)结构。当 x 增大到 1.00 时,晶粒尺寸减小,而晶粒尺寸和孔隙率增大,但与氧化锌的结果相当。随着 x 的增加,代拜温度、杨氏模量和能隙急剧下降,直到 x = 1.00 时达到最大值 623.14 K、952 GPa 和 3.45 eV(ZnO 为 650.39 K、17 GPa 和 3.28 eV)。x = 0.05 时,载流子密度增至 8.06 × 10 19 (cm-3),是氧化锌(1.07 × 10 19 (cm -3))的 8 倍。x = 0.00 时的 q 因子值最高(3.5 × 10 5),比氧化锌(3 × 10 4)高出约 10 倍。当 x 增加到 0.30 以上时,光导率明显增加,大于 ZnO。可见光发射峰的 PL 强度随 x 值的增加而逐渐增加,直到 x = 1.00 时高于 ZnO。当 x ≤ 0.30 时,样品会出现轻微的紫外光偏移,但当 x ≥ 0.60 时,紫外光偏移变为蓝色,与 ZnO 相似。与氧化锌相比,本样品非常适合用于塑性变形、太阳能电池、光发射、超级电容器和大功率操作。据我们所知,这项工作从未在其他地方进行过。
An investigation of n-type semiconductors based on optical and photoluminescence of pure and Al doped Pr:123 compound
With ZnO comparison, we report here an investigation of n-type semiconductors in terms of optical and photoluminescence (PL) analysis based on PrBa2Cu3-3xAl3xOy (AlPr:123) compound with (0.00 ≤ x ≤ 1.00). The structure is tetragonal of the samples with x ≤ 0.30 and changes to orthorhombic for x > 0.30, whereas it is wurtizite (hexagonal) for ZnO. As x increases to 1.00, the grain size is decreased, while the crystallite size and porosity are increased, but they are comparable with those obtained for ZnO. The Debye temperature, Young’s modulus and energy gap are drastically decreased by increasing x until reach to their maximum values of 623.14 K, 952 GPa and 3.45 eV for x = 1.00 (650.39 K, 17 GPa and 3.28 eV for ZnO). The x = 0.05 has increased the carrier density to 8.06 × 10 19 (cm−3), which is about 8-times higher than of ZnO (1.07 × 10 19 (cm −3). The highest value of q-factor (3.5 × 10 5) is obtained for x = 0.00, which is about 10-tims higher than of ZnO (3 × 10 4). As x increases above 0.30, the optical conductivity is significantly increased to be greater than that of ZnO. The PL intensity of the visible emission peaks was gradually increases against x until becomes higher than that of ZnO when x = 1.00. A slight UV shift is obtained for x ≤ 0.30 samples, but it changed to blue for x ≥ 0.60, which is typically similar to ZnO. As compared to ZnO, the present samples are strongly recommended for plastic deformation, solar cell, light emission, super-capacitor and high-power operation. To the best of our knowledge, the present work has never been done elsewhere.

期刊介绍:
Results in Physics is an open access journal offering authors the opportunity to publish in all fundamental and interdisciplinary areas of physics, materials science, and applied physics. Papers of a theoretical, computational, and experimental nature are all welcome. Results in Physics accepts papers that are scientifically sound, technically correct and provide valuable new knowledge to the physics community. Topics such as three-dimensional flow and magnetohydrodynamics are not within the scope of Results in Physics.
Results in Physics welcomes three types of papers:
1. Full research papers
2. Microarticles: very short papers, no longer than two pages. They may consist of a single, but well-described piece of information, such as:
- Data and/or a plot plus a description
- Description of a new method or instrumentation
- Negative results
- Concept or design study
3. Letters to the Editor: Letters discussing a recent article published in Results in Physics are welcome. These are objective, constructive, or educational critiques of papers published in Results in Physics. Accepted letters will be sent to the author of the original paper for a response. Each letter and response is published together. Letters should be received within 8 weeks of the article''s publication. They should not exceed 750 words of text and 10 references.
