Gel-incorporated PbS and PbI2 single-crystals

Gel-network/single-crystal composites formed in gel media

“…Liu等人 [27] 成 功 能 材 料 . 这 需 要 设 计 具 有 特 定 功 能 的 凝 胶 体 系 [59] , 也 需要逐步研究功能性的单晶 (如半导体晶 体 [51,52] Gel-grown method has been adopted to grow single crystals for over a century, and has triggered increasing interest with a large number of single crystals obtained. Some organisms construct their hard tissues where foreign macromolecules have been incorporated into the brittle crystals to enhance their mechanical properties.…”

Bulk-Heterojunction with Long-Range Ordering: C60 Single-Crystal with Incorporated Conjugated Polymer Networks

“…Inspired by this biomineralization strategy, calcite single-crystals are grown from hydrogels, leading to a three-dimensional penetration of gel networks inside the crystals without destroying the single-crystallinity . In addition, varieties of single-crystals have been obtained from gels and formed the similar interpenetrating structures. − Accordingly, in this work, we construct long-range ordered BHJs between the well-known BHJ model pair, poly­[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenvinylene] (MEH-PPV) as donor and C 60 as acceptor . Instead of one-step film fabrication through spontaneous phase separation, we adopt a two-step method.…”

PbI2 Nanosheets for Photodetectors via the Facile Cooling Thermal Supersaturation Solution Method

“…The low-dimensional PbI 2 nanostructures of nanosheets, nanowires, and nanobelts are well compatible with the traditional micro/nano fabrication processing and have broad application prospects. Recently, many physical and chemical approaches including melt method, , mechanical exfoliation, , and sol–gel and solution method , have been successfully used to synthesize the micro- and nano-structured PbI 2 crystals with outstanding performances. However, the high temperature applied in the melt method results in the polytype admixture and defects in crystals.…”
