“…In the vertical Bridgman method, the shape of the ampule directly affects the crystals' quality. 44 During the growth of organic crystals, it is commonly used in the upper end of the open, the lower end of the conical ampule, 45 and the purpose of the conical design is to screen high-quality seed crystals in the early stage of crystal growth, and high-quality crystals can eventually be obtained. It is necessary to maintain the stable status of organic raw materials at high temperatures.…”

Large-sized organic crystals used as scintillators have great potential for X-ray detection and medical diagnosis due to their excellent environmental stability, extremely short fluorescence decay time, and low radiation detection limit. However, poor crystallinity, slow crystal growth speed, and lack of high-quality seed crystals make it challenging to obtain large sizes with high quality. Here, the vertical Bridgman method was introduced to grow organic doped crystals where p-terphenyl was used as the host and six nitrogenous biphenyls were adopted as the dopants. Nitrogen-containing biphenyl-doped p-terphenyl crystals were cultured to get the dimension of Φ 12 mm × 40 mm. Fluorescence spectra show that dopant molecules with molecular packing structures similar to those of the host molecule can achieve successful doping with the host molecule. Under X-ray excitation, the organic doped crystals exhibit tunable luminescence characteristics from blue light (465 nm) to green light (498 nm). Our research provides a reference for achieving successful doping of host and dopant molecules through molecular design.

“…Notably, the concept of poled polymer was proposed, laying a foundation for the industrialization of SNLO materials. 9 Compared with inorganic NLO materials, there are various advantages of SNLO materials, such as low dielectric constant (generally lower than 5, 10,11 but greater than 28 inorganic crystals 12,13 ), approximation between low frequency and high frequency that can greatly accelerate the phase matching, laser damage threshold (LDT) value higher than 10 GW cm −1 , 2,14 mechanical property and machinability are exceptional, and can be made into thin films, pressed sheets, 15 fibers, 16 etc.…”
