He aha te meaWaikura Lutetiumwhakamahia mō?
Ngā tioata taiaho me ngā rauemi matua mō ngā taiaho totoka:
Ngā tono matua: Ko te Lu₂O₃ he rauemi tīmatanga matua mō te hanga tioata taiaho mahi-teitei pērā i te lutetium-doped yttrium konumohe garnet me te lutetium-doped yttrium lithium fluoride. Ko te tikanga ka whakaatuhia ēnei tioata hei Lu: YAG (Yttrium Konumohe Garnet) Lu: YLF rānei (Yttrium Lithium Fluoride).
Tikanga mahi: Ko ngā katote Lutetium (Lu³⁺) tonu kāore e whakamahia hei katote hohe (ngā pokapū tukunga laser). Heoi anō, hei wāhanga o te whatunga matrix, ka taea e rātou te whakarato i tētahi taiao whatunga tino pumau me te kiato. Ina tāpirihia ki ētahi atu katote whenua onge (pērā i te Nd³⁺, Yb³⁺, Er³⁺, Tm³⁺, Ho³⁺), ka whakaatuhia e ngā tioata e ahu mai ana i te Lu₂O₃:
Te kawe wera teitei: Ka tohatoha pai i te wera, ka taea te whakamahi i te taiaho mana nui me te whakaiti i ngā pānga o te arotahi wera.
Te pumau matū me te pumau ā-mīhini: Kia mau tonu te pono o ngā taiaho i roto i ngā taiao uaua mō te wā roa.
Ngā āhuatanga pūngao phonon tino pai: Ka pā ki te roanga o te ora o te taumata pūngao me te whai huatanga matū o ngā katote taiaho.
Ngā Whakamahinga: E whakamahia whānuitia ana ēnei taiaho i roto i te tukatuka rauemi ahumahi (te tapahi, te whakarewa, te tohu), te hauora (te pokanga kanohi, te maimoatanga kiri), te rangahau pūtaiao, te lidar, me te rangahau hanumi herenga inertial pea.

He mea nui tēnei karāhe mō te whakatika i te he o te tae i roto i ngā pūnaha whatu matatau (pērā i ngā whāinga karuārai, ngā karāhe kāmera papai, me ngā pūnaha tuhi whakaahua).
Ngā uku mārama: Ka taea te whakamahi i te Lu₂O₃ tonu, i te whakakotahitanga rānei me ētahi atu waikura (pērā i te Y₂O₃) hei hanga uku polycrystalline mārama. He rite te ōritetanga o te whatu me te whakawhiti mārama o ēnei uku ki ngā tioata takitahi, engari he nui ake te rahi, he kaha ake te miihini, ā, he iti ake te utu ki te whakarite. Kei roto i ngā tono ko ngā pāpāho whakanui laser, ngā matapihi infrared, ngā matapihi missile, me ngā atarangi rama kaha-teitei.
Ngā tāpiri uku hanganga: Ka taea te tāpiri i tētahi iti o te Lu₂O₃ hei āwhina i te whakapūmau, hei kaihoko hangarau rohe witi rānei hei whakapai ake i ngā āhuatanga miihini pāmahana-tiketike, te ātete waikura, me te ātete ngoki o ētahi atu uku matatau (pērā i te silicon nitride me te silicon carbide), ā, ka whakamahia i roto i ngā peera pāmahana-tiketike, ngā taputapu tapahi, me ngā wāhanga miihini turbine.
Te kite i te hihi me te scintillator:

Lutetium silicate: Lu₂SiO₅:Ce³⁺ me ōna tioata e ahu mai ana. Nā te kiato teitei (~7.4 g/cm³), te tau ngota whai hua teitei, te wā pirau tere, me te putanga mārama teitei, koinei te rauemi kite matatau rawa atu i roto i te tomography tukunga positron.
Lutetium yttrium aluminate: (Lu, Y) )₃Al₅O₁₂:Ce³⁺ uku. Mā te whakakotahi i ngā painga o te putanga mārama teitei, te pirau tere, te whakataunga pūngao pai, me ngā uku ka taea te hanga ki ngā rahi nui me ngā āhua uaua, e whakamahia whānuitia ana i roto i te whakaahua hauora (PET/CT), ngā whakamātautau ahupūngao pūngao-teitei, te haumarutanga whenua (matawai tueke/utunga), me te tuhi puna hinu.
Ngā Painga: Nā te nui o te tau ngota (71) o te lutetium ka taea e te rauemi te aukati i te photon pūngao-teitei (X-ray, gamma ray) tino pai, ka pai ake te pai o te kimi.
Ngā whākawa me ngā rauemi kanapa:
Ngā rauemi matihiko: Ka taea te whakamahi i te Lu₂O₃ hei matihiko whai hua mō ngā rauemi kanapa kua whakahohehia e te katote whenua-onge. Ina tāpirihia ki ngā katote europium (Eu³⁺), ka taea e ia te tuku i te kanapa whero tino parakore (te tihi matua ~611 nm) me te whānuitanga tukunga whaiti me te parakore o te tae.
Ngā Whakamahinga: E whakamahia whānuitia ana i roto i ngā hangarau whakaaturanga matatau (pēnei i ngā mata whakanui whakaahua hihi-X teitei-taumira hauora, ētahi momo whakaaturanga tukunga mara) me ngā whakamātautau hihi-ā-rangi (ngā tohu koiora, ngā pūoko). Nā tōna pumau matū me te pāmahana pai rawa atu ka roa te ora o te phosphor.
