Ngwa YAP
Nkọwa
YAP single crystal bụ ihe dị mkpa matriks nwere ọmarịcha ngwa anya na nke kemịkalụ nke yiri YAG single crystal.A na-eji kristal na-adịghị ahụkebe na metal ion doped Yap kristal mee ihe na laser, scintillation, ndekọ holographic na nchekwa data anya, ionizing radieshon dosimeter, mkpụrụ ihe nkiri na-ekpo ọkụ dị elu na mpaghara ndị ọzọ.

Nkọwa mkpụrụ nke YAP
Ngwa YAP na-ezo aka na mkpụrụ kristal nke yttrium aluminom perovskite (YAP) mere.YAP bụ ihe kristal sịntetik nke nwere yttrium, aluminom na atom oxygen haziri n'ụdị kristal perovskite.
A na-ejikarị substrate YAP eme ihe n'ụdị ngwa dị iche iche, gụnyere:
1. Scintillation detectors: YAP nwere ihe magburu onwe scintillation Njirimara, nke pụtara na ọ na-egbuke egbuke mgbe ekpughere ionizing radieshon.A na-ejikarị eriri YAP eme ihe dị ka ihe scintillation na ihe nchọpụta maka onyonyo ahụike (dị ka positron emission tomography ma ọ bụ igwefoto gamma) na nnwale physics dị elu.
2. Laser steeti siri ike: Enwere ike iji kristal YAP mee ihe dị ka mgbasa ozi na-enweta na lasers steeti siri ike, ọkachasị na ogologo ogologo ndụ ndụ ndụ ma ọ bụ acha anụnụ anụnụ.Ihe ntanetị YAP na-enye ikpo okwu kwụsiri ike na nke na-adịgide adịgide maka ịmepụta ọkụ laser nwere ike dị elu yana àgwà dị mma.
3. Electro-optic na acousto-optic: Enwere ike iji ihe ndị YAP mee ihe na ihe dị iche iche nke electro-optic na acousto-optic, dị ka modulators, switches na frequency shifters.Ngwa ndị a na-erigbu njirimara nke kristal YAP iji jikwaa nnyefe ma ọ bụ mgbanwe nke ọkụ site na iji mpaghara eletriki ma ọ bụ ebili mmiri ụda.
4. Ndị na-achọpụta ụzarị ọkụ nuklia: A na-ejikwa ihe ndị YAP na-achọpụta ihe na-achọpụta radieshon n'ihi ihe ha na-ahụ anya.Ha nwere ike ịchọpụta ma tụọ ike nke ụdị radieshon dị iche iche, na-eme ka ha baa uru na nyocha physics nuklia, nlekota gburugburu ebe obibi, na ngwa ahụike.
Ihe ntanetị YAP nwere uru nke mmepụta ọkụ dị elu, oge ire ere ngwa ngwa, mkpebi ike dị mma, na nnukwu iguzogide mmebi radieshon.Ngwongwo ndị a na-eme ka ha dị mma maka ngwa na-achọ scintillator dị elu ma ọ bụ ihe laser.
