Synthesis and photoluminescence of semiconductor ZnSe hollow microspheres by two-sourced evaporation

Structure and optical properties of SiO2 films with ZnSe nanocrystals formed by ion implantation

“…Following the demonstration of possible application of zinc selenide in photoelectronic devices, an intensive attention is paid to ZnSe as an alternative to the more toxic Cd-based materials. Indeed, ZnSe-based materials in such forms as thin films, nanocrystals (NCs), quantum wells, flower-shaped nanocrystals [1], nanoribbons [2], nanowires [3], hollow microspheres [4] and bulk crystals are applicable for fabrication of blue and green light-emitting diodes due to the direct band gap, infrared windows due to wide transmission wavelength range, lenses and prisms, and optically controlled switching devices due to giant photoresistivity.…”

Synthesis of grass-like ZnSe nanostructures on graphene oxide and their excellent field emission properties

“…ZnSe nanostructures have been achieved by several methods, such as thermochemical method [8], atomic layer deposition method [11], solvothermal processes [12], and hydrothermal method [13]. In hydrothermal and solvothermal processes, the morphology of the as-grown samples can be easily influenced by some additives such as ethylene diamine tetraacetic acid (EDTA) [14], diethanolamine [15], and hydrazine hydrate (N 2 H 4 Á 2H 2 O) [16].…”

Solvothermal synthesis of well-dispersed ZnSe microspheres

“…12 [39,44,45]. The emission bands at 398 nm, 416 nm, and 496 nm are usually assigned to self-activated luminescence, probably as a result of some donor-acceptor pairs related to Zn/Se-vacancies and interstitial states [28,30,46]. Besides, the emission bands gap energy may be attributed to the differences of shapes or sizes of ZnSe crystal.…”

“…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.…”
