Abstract

Disclosed are a preparation method for a quantum dot, a preparation method therefor, and a light-emission material film. Controlling a dimension of a luminescent core of a core-shell quantum dot to be 10 nm to 20 nm may improve a blue light absorption rate and a light extraction efficiency during a light conversion process, such that an use amount of a quantum dot material in a device may be reduced, thereby saving a material cost. In addition, since the dimension of the luminescent core is larger than an exciton bohr diameter, a binding effect of excitons in a core is greatly improved, thus reducing a probability of excitons being quenched by interface defect states, and improving water-resistance and oxygen-resistance stability of the quantum dot material.

Abstract

The present disclosure provides a film, an optoelectronic device, and a display device. The film includes a first modified material and an N-type semiconductor material, and the first modified material includes at least one of maleimide and a maleimide derivative. The first modified material may function as an electron acceptor because of the small electron density (electron deficiency), and the N-type semiconductor material may function as an electron carrier because of the better conductivity. Electrons are easily transferred from the electron carrier to the electron acceptor, that is, electrons are easy to flow between the N-type semiconductor material and the first modified material, thereby the film may have better electron transport performance. When the film is applied to the optoelectronic device, the electrical performance of the optoelectronic device may be improved.

Abstract

The present disclosure film, preparation method thereof and photoelectric device. The film includes a nanocellulose and an inorganic nanoparticle, wherein the nanocellulose has a porous skeleton, and the inorganic nanoparticle is located in pores of the porous skeleton. By doping the nanocellulose with toughness into the inorganic nanoparticle, the inorganic nanoparticle can be embedded into the skeleton of the nanocellulose to limit the movement of the inorganic nanoparticle, so that the displacement of the inorganic nanoparticle during the bending process of the film can be reduced. And the situation that the film is cracked or broken during the bending process can be slowed down or eliminated, thereby improving the bending resistance of the film. When the film is applied to a flexible photoelectric device, the service life of the flexible photoelectric device can be prolonged because the film has good bending resistance.

Abstract

A system and method for video temporal action proposal generation are provided. It processes video features extracted from the input video through an encoder to obtain video encoding features with global information, extracts corresponding interest segment features from the video encoding features using pre-trained proposal segments, and provides them to the decoder. The decoder generates segment features based on the interest segment features corresponding to each proposal segment and the pre-trained proposal features. These are then provided to the prediction module, generating temporal action proposal results based on the decoder's segment features. The solution in embodiments of the present invention can effectively capture global context information of the video, obtaining video encoding features with stronger representational capabilities. By introducing the several learnable proposal segments to extract the corresponding position-based feature sequences from the video encoding features, the training convergence speed is enhanced, and computational burden is reduced.
