| 1 | Unidirectionally aligned bright quantum rods films,using T-shape ligands,for LCD application显示文摘Unidirectionally aligned nanorods(NRs)are of great importance for different applications,including displays,lighting,and photodetectors.Recently,many alignment techniques were studied to align quantum rods(QRs).However,the brightness of these films,due to the limited concentration of aligned quantum rods in the film,is not enough for their implementation as brightness enhancement films(BEFs)in displays.This can be ascribed to the poor miscibility of quantum rods in polymer and strong concentration dependence of the polarized emission.The ligands of NR are very important for the alignment and brightness.In this article,we proposed a ligand combination comprising T-shape promesogenic phosphonic acid,which on being photoaligned provides mutually parallel alignment of the quantum rods.The T-shape ligands enable the fabrication of hybrid films with a QRs concentration as high as 10 wt.%–20 wt.%retaining high brightness and luminescence polarization property.Later,we used these films in the in-plane switching(IPS)display backlight that shows the color gamut up to 121%of national television system committee(NTSC)(CIE1931),liquid-crystal display(LCD)efficiency up to 7.9%,power efficacy 103±2 nits/W,and the high brightness of~550±10 nits.Thus,the proposed ligands can be used for the alignment of a variety of nanorods. | Maksym F.Prodanov Chengbin Kang Swadesh K.Gupta Valerii V.Vashchenko Yuhao Li Minchao Qin Xinhui Lu Abhishek K.Srivastava | 2022 | Nano Research2022，15，6： | 0 |
| 2 | Photo-induced flexible semiconductor CdSe/CdS quantum rods alignment显示文摘The anisotropic absorption and emission from semiconductor CdSe/CdS quantum rods(QRs)provide extra benefits among other photoluminescence nanocrystals.Using photo-induced alignment technique,the QRs can be oriented in liquid crystal polymer matrix at a large scale.In this article,a 2D Dammann grating pattern,within“SKL”characters domains aligned QRs in composite film,was fabricated by multi-step photo exposure using several photo masks,and a continuous geometric lens profile pattern aligned QRs was realized by the single step polarization converting holographic irradiation method.Both polarized optical microscope and fluorescence microscope are employed to determine the liquid crystal director profiles and QRs anisotropic excitation properties.We have been able to orient the QRs in fine binary and continuous patterns that confirms the strong quantum rod aligning ability of the proposed method.Thus,the proposed approach paves a way for photoinduced flexible QRs alignments to provide a highly specific and difficult-to-replicate security application at a large scale. | Wanlong Zhang Julian Schneider Maksym F.Prodanov Valerii V.Vashchenko Andrey L.Rogach Xiaocong Yuan Abhishek K.Srivastava | 2023 | Journal of Semiconductors2023，44，9： | 0 |
