Obvious LITV keeps a linear increase with the increased power density for each wavelength laser. The peak voltage is over 40 mV at the power density of 40 mW/cm². It is slightly different with the laser wavelength, caused by the difference in optical absorption and light penetration depth. The sensitivity is higher than 0.8 and increases to 1.15 V·cm²/W with the laser changes from green to ultraviolet. Furthermore, based on the LITV effect of the BSCO thin film, the carry information can be transmitted and decoded correctly via the optical communications system composed of the light diode laser.

The structural, morphological, and chemical properties of the materials were thoroughly investigated using X-ray diffraction (XRD), scanning/transmission electron microscopy (SEM/TEM), and energy dispersive X-ray (EDX) analysis. The crystallite sizes of the Gd-doped and Mn-doped samples were 46 nm and 59 nm, respectively. XRD analysis confirmed that both samples exhibited a single monoclinic phase crystal structure. The Gd-doping resulted in a more uniform particle size distribution and smoother surface morphology, which could enhance the optical and magnetic properties of the material. In contrast, Mn-doping led to the formation of more agglomerated particles with a rougher texture, potentially affecting the specific surface area and its interaction with external fields. SEM/TEM images also revealed an increase in average particle size with the Mn dopant. Optical properties, as measured by diffuse reflectance spectroscopy (DRS), showed a band gap of 3.79 eV for ZnWO₄: Gd and 3.40 eV for ZnWO₄: Mn. Magnetic measurements indicated enhanced magnetic properties for ZnWO₄: Mn compared to both pure ZnWO₄ and ZnWO₄: Gd. The dielectric properties, including the dielectric constant (εr), dielectric loss (tan δ), and AC conductivity, were studied over a frequency range from 100 Hz to 3 MHz at room temperature. The reduced coercivity observed in the Mn-doped sample suggests improved performance for potential applications in transformers, windings, and magnetic storage devices, where reduced core loss and enhanced efficiency are key requirements.This study not only enhances the understanding of the influence of Gd and Mn doping on ZnWO₄ properties but also opens up new possibilities for the development of multifunctional materials for advanced technological applications.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":473,"journal":{"name":"Applied Physics A","volume":"131 5","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143749175","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, laser processing emerges as an effective method for diamond machining, where the laser pulse width plays a crucial role in determining processing efficiency and quality. In this study, we utilized lasers with different pulse widths ranging from 300 fs to 3 ps, to perform microgrooving on the surface of a single-crystal diamond. Our research focused on evaluating various aspects, including the ablation threshold, material removal rate (MRR), microgroove dimensions, surface morphology, bottom region roughness, and material removal mechanisms of single-crystal diamonds under different laser pulse widths. The primary objective was to investigate the processing characteristics and the corresponding variations of single-crystal diamonds under these different laser pulse width conditions. The results of our study reveal that ultra-short pulse lasers with varying pulse widths significantly influence the ablation threshold, MRR, microgroove dimensions, surface morphology, and roughness of diamonds through their peak power. Remarkably, reducing the laser pulse width from 3 ps to 300 fs resulted in an impressive 75% decrease in the diamond ablation threshold. Additionally, the microgroove dimensions and <i>MRR</i> demonstrated gradual increments. Particularly, during the high average power stage, the influence of pulse width on groove depth and <i>MRR</i> became more pronounced due to incubation effects and plasma shielding. Another notable finding was the evolution of the surface morphology of diamond microgrooves, transitioning from periodic ripple structures to the appearance of damage, cracks, and even microgroove fragmentation. Moreover, the roughness (Rz) of the microgroove bottom region increased from 40 to 264 nm. While the effect of laser pulse width on the material removal mechanism of diamond was relatively weak, it was observed to induce less subsurface damage (sp³ + sp²). Additionally, in our experimental conditions, we detected the involvement of oxygen in the laser processing of diamonds. However, the main material removal mechanisms were identified to be evaporation or sublimation.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":473,"journal":{"name":"Applied Physics A","volume":"131 4","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143740847","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

X-ray diffraction reveals that the compound has a well-defined crystalline structure in the monoclinic phase having a C2/c space group. Scanning electronic microscope indicated a compact microstructure and well grown grains separated by grain boundaries.

Over a temperature range of 353–573 K, the conductivity measurements of the produced ceramic are examined. In addition, the Nyquist plots revealed contributions from both the grains and the grain boundaries suggesting that the material demonstrates a relaxation behaviour characteristic of the non Debye type and provide reasons supporting the semi conducting nature of this sample. In addition, dielectric analysis demonstrated significant frequency-dependent behavior, characterized by various polarization effects and relaxation phenomena. Jonscher’s power law is used to analyze alternating current and conductivity, and it is found that the fluctuation of the exponent “s” adequately describes the conduction mechanism and agrees with CBH models.
