Simultaneous growth of ZnSe cactus-like structures and novel microflowers of selenium

Wide Range Photodetector Based on Catalyst Free Grown Indium Selenide Microwires

“…One-dimensional (1D) crystal structures are important for optoelectronics and future nanoscale devices as they allow interconnections within their size limits. − There are reports on nanoscale device fabrication and these devices have shown significant progress in building a new generation of electronic and photoelectronic systems. − Photodetectors are necessary devices in memory storage and optoelectronic circuits and various semiconducting materials like group III-V compounds and group II-VI compounds − have been used in fabricating photodetectors but are limited due to poor efficiency.…”

Zinc selenide nano- and microspheres via microwave-assisted ionothermal synthesis

“…Thiols, phosphines and amines have been used as capping agents, with continuous stirring for 36 hours and subsequent drying for 8-10 hours at 120 C. A direct thermal route can also be used through heating the elemental precursors in ammonia under an ammonia atmosphere at 500 C for several hours. 11 The microwave reactor has also been implemented in the formation of zinc selenide nanomaterials, which has numerous advantages over traditional thermal methods including fast and homogeneous heating of the reaction mixture, high speed of interaction, an inverse temperature gradient and the possibility of fast selection of chemical reaction conditions. 12 Microwave irradiation is different from other techniques in that it does not rely on black body radiation to heat the reaction mixture, which allows for greater advantages for colloidal nanostructured materials to be formed.…”

Solvothermal synthesis of well-dispersed ZnSe microspheres

“…Moreover, solvents, organic additives, and surfactants have important effects on the shape-and sizecontrolled synthesis of inorganic particles [23][24][25][26][27]. Although a few contributions have appeared on the synthesis of various morphological ZnSe, including hollow nanospheres/microspheres, nanowires, nanobelts and branched heterostructure, nanorods, flowerlike, and so forth [28][29][30][31][32][33][34][35][36][37][38][39], there have been few studies on fabrication of ZnSe spheres via surfactant-assisted solvothermal method. Herein, in this paper, we report a facile, convenient, and reliable solvothermal method to synthesis stilleite structure ZnSe microspheres.…”
