Ngwa YVO4
Nkọwa
YVO4 bụ ezigbo kristal birefringent maka ngwa fiber optics.Nke nwere ezigbo okpomọkụ kwụsie ike na anụ ahụ na n'ibu Njirimara.Ọ dị mma maka akụrụngwa polarizing anya n'ihi oke nghọta ya na nnukwu birefringence.Ọ bụ ezigbo ihe mgbakwunye sịntetik maka Calcite (CaCO3) na kristal Rutile (TiO2) n'ọtụtụ ngwa gụnyere fiber optic isolators na circulators, interleavers, beam displacers and other polarizing optics.

Nkọwa mkpụrụ okwu YVO4
Mkpụrụ YVO4 (Yttrium Orthovanadate) na-ezo aka na ihe kristal a na-ejikarị na ngwa anya na ngwa optoelectronic dị iche iche.Nke a bụ ụfọdụ isi ihe gbasara ihe YVO4:
1. Ọdịdị kristal: YVO4 nwere usoro kristal tetragonal, na yttrium, vanadium, na ikuku oxygen na-ahazi n'ime oghere atọ.Ọ bụ nke usoro kristal orthorhombic.
2. Nfefe ọkụ: YVO4 nwere oke nnyefe ọkụ, site na nso ultraviolet (UV) na mpaghara etiti infrared (IR).Ọ nwere ike ibunye ọkụ site na ihe dịka 0.4 μm ruo 5 μm, na-eme ka ọ dị mma maka ọtụtụ ngwa ngwa anya.
3. Birefringence: YVO4 nwere ike birefringence, ya bụ, ọ nwere dị iche iche refractive indices maka dị iche iche polarized ìhè.Ngwongwo a dị oke mkpa maka ngwa dị ka ebili mmiri na ihe nzacha polarizing.
4. Ngwongwo anya na-adịghị anya: YVO4 nwere ihe ndị dị mma na-enweghị atụ.Ọ nwere ike ịmepụta ugboro ọhụrụ ma ọ bụ gbanwee njirimara nke ọkụ merenụ site na mkparịta ụka na-adịghị.A na-eji ihe onwunwe a na ngwa dị ka ugboro abụọ (ọgbọ nke abụọ harmonic) nke lasers.
5. Ọnụ ụzọ mmebi nke laser dị elu: YVO4 nwere ọnụ ụzọ mmebi laser dị elu, nke pụtara na ọ nwere ike iguzogide ogwe ọkụ laser dị elu na-enweghị nnukwu mmebi ma ọ bụ mmebi.Nke a na-eme ka ọ dị mma maka ngwa laser dị elu.
6. Thermodynamic Njirimara: YVO4 nwere ezigbo nkwụsi ike nke okpomọkụ na ike nrụpụta, na-enyere ya aka iguzogide mgbanwe okpomọkụ na nrụgide ígwè na-enweghị nnukwu nrụrụ ma ọ bụ mmebi.
7. Nkwụsi ike nke kemịkalụ: YVO4 nwere nkwụsi ike nke kemịkal ma na-eguzogide ọgwụ na-edozi ahụ na acids nkịtị, na-eme ka ọ dị ogologo na ntụkwasị obi n'okpuru ọnọdụ ọrụ dị iche iche na gburugburu ebe obibi.
A na-eji ihe ndị YVO4 eme ihe n'ọtụtụ ebe na ngwa dị ka sistemu laser, ngwa ngwa anya, ndị na-atụgharị ugboro ugboro, ndị na-eke ọkụ, na efere ifegharị.Ngwakọta ya nke nghọta anya anya, birefringence, ihe ndị na-ahụ anya na-adịghị ahụ anya, ọnụ ụzọ mmebi laser dị elu, na ezigbo okpomọkụ na nkwụsi ike na-eme ka ọ bụrụ ihe dị iche iche n'ọhịa nke optics na optoelectronics.
