This application belongs to the field of saturable absorber technology, and particularly relates to a saturable absorber based on tantalum arsenide quantum dots, its preparation method, and a mode-locked fiber laser. The saturable absorber provided by this application includes a tapered optical fiber and tantalum arsenide quantum dots loaded thereon. The tantalum arsenide quantum dots have excellent nonlinear optical properties and saturation intensity, so when the laser passes through the tantalum arsenide quantum dots on the saturable absorber, the laser reaches saturation quickly, enabling the output of ultrafast laser with a repetition frequency and stable laser mode-locked signal, thereby solving the technical problem of low performance of saturable absorbers based on two-dimensional materials in the prior art.

This invention provides a display panel and display device, comprising: a substrate, a planarization layer, an anode layer, and a pixel definition layer stacked sequentially. The pixel definition layer includes a flat region, several exposed opening regions, and a ramp region disposed between the flat region and the opening regions. The opening regions expose the central region of the anode layer. A light-emitting layer is patterned in the opening regions, on the side of the anode layer facing away from the substrate. A reflective layer is patterned in the side of the pixel definition layer facing away from the substrate, and the reflective layer only exposes the light-emitting layer. At least a portion of the emitted light from the light-emitting layer is reflected by the local reflective layer and guided in a direction perpendicular to the substrate. A transparent cathode layer is formed on the side of the light-emitting layer and the reflective layer facing away from the substrate. This invention solves the problem of light escaping or being absorbed through the pixel definition layer, guiding the emission direction of laterally emitted light to a vertical direction, thereby improving the light extraction efficiency.

This application belongs to the field of saturable absorbers, and particularly relates to a saturable absorber based on tantalum nitride quantum dots, its preparation method, and a mode-locked fiber laser. The tantalum nitride quantum dots in the saturable absorber provided by this application, as topological half-metals, exhibit excellent optical properties and saturation intensity. When a laser beam passes through the tantalum nitride quantum dots on the saturable absorber, the laser can quickly reach saturation, enabling the output of ultrafast lasers with a repetition frequency and stable laser mode-locking signal. This solves the technical problem of low performance in existing saturable absorbers based on two-dimensional materials.

This invention relates to the field of traditional Chinese medicine preparation technology, specifically to a blood-activating and meridian-clearing traditional Chinese medicine composition with agarwood as the principal ingredient. The composition comprises the following raw materials in parts by weight: 5-15 parts modified agarwood complex, 40-60 parts compound extract powder, 1-3 parts broken-cell-wall scorpion powder, 20-50 parts filler, and 0.5-2 parts lubricant. This invention improves the efficient release of the effective components of agarwood as the principal ingredient by using the modified agarwood complex, ensuring the stability of the core efficacy of agarwood and extending the retention time of its core components. The addition of compound extract powder scientifically combines blood-activating and blood-nourishing herbs, ensuring powerful meridian clearing while replenishing qi and blood, reducing the side effects of long-term medication, and improving patient safety. The broken-cell-wall scorpion powder reduces the risk of sensitization and poisoning, breaking the cell walls of the scorpion to fully release the core analgesic peptides and antithrombotic peptides, thus improving gastrointestinal absorption efficiency.
