Izinto ze-Tellurium dioxide, ikakhulukazi izinga eliphezulu le-nano-levelI-Tellurium oxide, ziye zadonsa ukunaka kwabantu abaningi embonini. Ngakho yiziphi izici ze-nano Tellurium Oxide, futhi iyiphi indlela eqondile yokulungiselela? Ithimba le-R & D leUkulinganisa kwenkampani UrbanMines Tech Co., Ltd.ifinyeze lesi sihloko ukuze ibhekisele embonini.
Emkhakheni wesayensi yezinto ezibonakalayo, i-tellurium dioxide, njengento enhle kakhulu ye-acousto-optic, inezici ze-high refractive index, inguquko enkulu ye-Raman ehlakazekayo, ama-optics amahle angenayo i-nonlinear, ukuhamba kahle kukagesi, izakhiwo ezinhle kakhulu ze-acoustoelectric, ukudluliswa okuphezulu kwangaphakathi kwe-ultraviolet kanye ukukhanya okubonakalayo, njll. I-Tellurium dioxide isetshenziswa kakhulu kuma-amplifiers optical, ama-acousto-optic deflector, izihlungi, ukuguqulwa kokubona...
Ama-Nanomatadium anezici zendawo enkulu ethize kanye nosayizi wezinhlayiyana ezincane, ezingayenza ikhiqize imiphumela engaphezulu, imiphumela ye-quantum kanye nemiphumela yosayizi. Ngakho-ke, ucwaningo olujulile nge-tellurium dioxide nanomaterials ludingeka kakhulu.

Ngakho-ke, ucwaningo olujulile nge-tellurium dioxide nanomaterials ludingeka kakhulu. Njengamanje, izindlela zokulungiselelai-tellurium dioxideAma-nanomaterials ahlukaniswe kakhulu ngendlela yokuhwamuka okushisayo kanye nendlela ye-sol. Indlela ye-evaporation eshisayo iyinqubo yokuhwamuka ngokuqondile kwe-elemental tellurium powder eqinile ngaphansi kwezimo eziphakeme zokushisa ukuze uthole i-oxide entsha. Ububi buwukuthi ukusabela kudinga izinga lokushisa eliphezulu, okokusebenza kuyabiza, futhi kukhiqizwa umhwamuko onobuthi. Ama-nanomaterials amaningi e-tellurium dioxide alungiswe ngokuhwamuka. Izinhlayiya ze-Te elemental ziyahwamuka ngokusebenzisa ilangabi le-plasma ye-microwave yomoya ukuze kulungiswe ama-nanoparticles ayindilinga we-tellurium dioxide anokusabalalisa usayizi wezinhlayiyana ongu-100-25nm. Park et al. i-Te elemental powder ehwamukile kushubhu lequartz elingavaliwe ku-500 ° C, yashintsha ifilimu ye-Ag ebusweni be-SiO2 nanorods, yalungisa i-Ag functionalized tellurium dioxide nanorods enobubanzi obungu-50-100nm, futhi yayisebenzisa ukuthola ukugcwala kwegesi ye-ethanol. . Indlela ye-sol isebenzisa impahla ye-tellurium precursors (imvamisa i-tellurite ne-tellurium isopropoxide) ukuze i-hydrolyzed kalula. Isistimu ye-sol ekhanyayo ezinzile iyakhiwa ngemva kokwengeza i-acid catalyst ngaphansi kwezimo zesigaba soketshezi. Ngemuva kokuhlunga nokomisa, kutholakala i-tellurium dioxide nano-solid powder. Indlela ilula ukuyisebenzisa, ihambisana nemvelo, futhi ukusabela akudingi izinga lokushisa eliphezulu. Sebenzisa izakhiwo ze-asidi ezibuthakathaka ze-acetic acid ne-gallic acid ukuze uvuselele futhi wenze i-Na2TeO3 i-hydrolyze ukuze ulungise i-tellurium dioxide nanoparticle sol, futhi uthole ama-nanoparticles e-tellurium dioxide ahlukahlukene amafomu e-crystal, anobukhulu bezinhlayiyana kusukela ku-200-300nm.
