Ngā kohatu hapira tae-taiwhanga Whakapaipai me ngā pouaka mataaratanga Magenta kua whakaritea Whakaahua Matua

Whakaahuatanga Poto:

Ka hangaia te sapphire tae-whakatipu-ā-roto (Magenta hue) mā te whakamahi i te hangarau matatau o te Hydride Vapor Phase Epitaxy (HVPE), ka tutuki ai ngā āhuatanga ā-tinana-matū e rite ana ki te sapphire Magenta tūturu. Mā te whakahaere tika i ngā kukū tāpiri chromium (Cr³⁺: 0.3-0.7wt%) me te titanium (Ti⁴⁺: 0.05-0.15wt%) me te aroturuki i te Raman spectroscopy wā-tūturu, ka whakaatuhia e ēnei tioata he tae magenta pumau (CIE x=0.35-0.38, y=0.25-28; roangaru matua 610±5nm, kōhua 85±5%). Ka whakaatuhia e te rauemi te pakeke Mohs 9 (Vickers 2200-2300HV), te pumau wera tino pai (-200°C ki te 800°C me te kore e memeha), me te tuku mārama pai rawa atu (>82% @400-700nm). He tino pai te karaihe (ngā whakaurunga <0.001%) i ngā mea tūturu, ā, he kaha hoki ki te whakaputa i ngā boule 80mm te whānui (te hua 78%), ko tēnei hapaira hangarau he putanga hou mō ngā pouaka mataaratanga papai, ngā wāhanga rererangi, me ngā tono whatu matūriki.

2. Te Mahi Tinana

· Te pakari o te taiao: <0.5% te ngaronga whakawhiti i muri i te 1000 huringa wera (-200°C↔200°C); kāore he tae i muri i te 100h @800°C

· Kaha ā-ringa: Kaha pēhi 2.5GPa me te kaha piko >2GPa (10× quartz) e tu atu ana i ngā whakamātautau maturuturu 5000

3. Kounga Karaihe

· Whakahaere hapa: Ko ngā tawhā whatunga kua whakaūtia e te XRD (a=4.758Å, c=12.991Å) e ōrite ana ki te JCPDS#41-1468 me te ōritetanga >99.9%; E whakaatu ana te TEM i ngā wātea hāora <10¹⁵/cm³

· Āhuatanga Tauine: 40% teitei ake te hua i te tikanga Czochralski mō ngā boule 80mm (15kg te taumaha karaihe kotahi)

4. Te Āheinga Mīhini

· Te hanga tika: Ka whakairohia e te CNC ngā āhuatanga iti 0.1mm (hei tauira, ngā taputapu tourbillon) e tutuki ana i te ISO 2768-m; ka tutuki i te whakairo laser te tika ±1μm

· Whakaotinga mata: Ka tukuna e te oro MRF te Ra<0.8nm me te ātete ki te rakuraku Mohs 9 (kawenga 1kg, kōhao <1μm)

Ngā Taupānga Matua

1. Haute Horlogerie

- Auahatanga o te pouaka mataaratanga: Ka whakaitihia e te "tapahi Biconic" te matotoru o te pouaka 45mm ki te 1.2mm (ki te 2.5mm noa) me te whakanui ake i te kaha piko ki te 2.2GPa

- Whakaurunga mahi: Ka taea e ngā kiriata ITO kua pakaru (<80Ω/□) te whakahohe i ngā karauna pā-pā me te 85% te pai o te utu ahokore
