Piv nrognormal LNsiv lead ua(CLN)nrog tib lub ntsiab lus, qhov tsis muaj lithium nyob ze-stoichiometricLNsiv lead ua(SLN)ua rau kom txo qis hauv cov lattice defects, thiab ntau yam khoom hloov raws li.Cov lus hauv qab no teev cov ntsiab lus tseem ceebqhov sib txawv ntawmlub cev muaj zog.
Kev sib piv ntawm Cov Khoom ntawm CLN thiab SLN
| Khoom | CLN | SLN |
| Kev sib txuas lus / 633nm | -0.0837 | -0.0974 (Li2O = 49.74 mol%) |
| EO coefficient / teev•V-1 | r61= 6.07 | r61= 9.89 (Li2O = 49.95 mol%) |
| Nonlinear coefficient /pm•V-1 | d33= 19.5 | d33= 23.8 |
| Photorefractive saturation | 1×10-5 | 10×10-5 (Li2O = 49.8 mol%) |
| Photorefractive teb lub sij hawm /s | pua | ～0.6 (Li2O = 49.8mol%, hlau doped) |
| Photorefractive kuj / kW•cm-2 | 100 | 104 (Li2O = 49.5-48.2mol, 1.8mol% MgO doped) |
| Domain ntxeev hluav taws xob teb siv /kV•mm-1 | 21 | 5 (Li2O = 49.8 mol%) |
Piv nrogCLNnrog tib muaj pes tsawg leeg, feem ntau ntawm cov khoom ntawmSLNtau raug txhim kho mus rau qhov sib txawv.Qhov tseem ceeb tshaj optimization muaj xws li:
(1) Whether photorefractive doping, anti-photorefractive doping lossis laser-activated ion doping,SLN muajntau rhiab kev ua tau zoo tswj cov nyhuv.Kong et al.pom tias thaum [Li] / [Nb] nce mus txog 0.995 thiab cov ntsiab lus magnesium yog 1.0mol%, photorefractive tsis kam ntawmSLNtuaj yeem ncav cuag 26 MW / cm2, uas yog 6 qhov kev txiav txim siab ntau dua li ntawmCLNnrog tib lub ntsiab lus.Photorefractive doping thiab laser-activated ion doping kuj muaj cov teebmeem zoo sib xws.
(2) Raws li tus naj npawb ntawm lattice defects hauvSLNsiv lead ua txo qis, yog li qhov coercivity teb lub zog ntawm cov siv lead ua, thiab qhov hluav taws xob xav tau rau polarization thim rov qab los ntawm kwv yees li 21 kV / mm(ntawm CLN)mus txog 5 kV / mm, uas yog qhov zoo heev rau kev npaj cov khoom siv superlattice.Ntxiv mus, hluav taws xob domain qauv ntawmSLNyog li niaj zaus thiab cov phab ntsa sau yog smoother.
(3)Muaj ntau photoelectriccov khoom ntawmSLNkuj tau txhim kho zoo heev, xws li electro-optic coefficientr61nce 63%, nonlinear coefficient nce 22%, crystal birefringence nce 43% (wavelength 632.8 nm), xiav hloovntawm UVabsorption ntug, thiab lwm yam.
