Air-stable luminescent organic-inorganic perovskite nanocrystal-polymer composites
The technology realizes a perovskite nanocrystal-polymer composite material, which has extremely high stability at room temperature and high temperature. It can be used for 3D printing, shaped into fluorescent microfilaments, and can also be used for white light-emitting diodes. The application of this air-stabile perovskite nanocrystal-polymer composite material in the 3D printing industry, textile industry and electronics industry has subverted the impression that the characteristics of perovskite nanoparticles are extremely prone to decay.The instability of perovskite materials in the air is a great stumbling block in its application. The contribution of this technology lies in the realization of a perovskite nanocrystal-polymer composite, which has a high stability in the air at room temperature. It can also emit light even if it is placed in boiling water. Compared with the stability generally available in the world, this composite material can be boiled has been a big breakthrough. It is unprecedented that this composite can be used for 3D printing and fluorescent microfilament fabrication.The technology realizes a perovskite nanocrystal-polymer composite, which not shows high stability in room temperature air. It can also emits light after putting in boiling water for more than 10 minutes. After reforming the composite material into a linear wire, it can be used for 3D printing to prepare the desired patterns or objects. This technology also uses this composite material to prepare fluorescent microfilaments and white light-emitting diodes, contributing to the 3D printing, textile, and electronics industries.
National Taiwan Normal University (NTNU) is a national comprehensive university in Taipei and New Taipei City, Taiwan.[5] NTNU is affiliated with National Taiwan University and National Taiwan University of Science and Technology as part of the National Taiwan University System.[6] NTNU is a member of University Academic Alliance in Taiwan,[7] International Consortium for Universities of Education in East Asia,[8] University Alliance in Talent Education Development,[9] and AAPBS.[10] The university enrolls approximately 17,000 students each year. Approximately 1,600 students are international. 1,000 students are overseas Chinese in preparatory programs.[11] The Research Center for Psychological and Educational Testing (RCPET) at NTNU is responsible for organizing Taiwan's annual Comprehensive Assessment Program for Junior High School Students (CAP).[12] NTNU is also the convening institution for the Committee of College Admission Practical Examination, which is responsible for conducting practical examinations in the fields of fine arts, music, and physical education for use in university admissions across Taiwan.[13] Mandarin Training Center (MTC) is the oldest and the largest Chinese language teaching institution in Taiwan.[14] The Test of Chinese as a Foreign Language (TOCFL) is administered by the Steering Committee for the Test Of Proficiency-Huayu (SC-TOP) at NTNU.[15]
