Tam sim no Breakthroughs nyob rau hauv Optical Applications ntawm Boron Nitride Materials

Nyob rau hauv xyoo tas los no, boron nitride (BN) tau tshwm sim los ua ib qho khoom cog lus rau kev siv kho qhov muag vim nws cov khoom tshwj xeeb, xws li thermal stability siab, qis refractive index, thiab siab transparency nyob rau hauv lub ultraviolet, pom thiab infrared spectral cheeb tsam.

Ib qho ntawm kev ua tiav hauv daim ntawv thov BN hauv qhov chaw kho qhov muag yog nws txoj kev ua tiav zoo nrog graphene. Kev sib xyaw ua ke ntawm BN thiab graphene tsim cov qauv hybrid nrog cov khoom tsim nyog, suav nrog kev pom qhov pom kev siab, zoo thermal conductivity, thiab siab mechanical zog. Qhov no tau qhib qhov muaj peev xwm los tsim cov khoom siv optoelectronic tshiab xws li cov qhov rais ntse thiab cov duab hloov tau.

Lwm qhov kev nce qib tseem ceeb hauv kev siv BN rau kev siv kho qhov muag yog kev txhim kho ntawm BN nanotubes. Cov nanotubes, nrog rau lawv qhov sib piv siab, thaj chaw loj, thiab cov khoom siv kho qhov muag tunable, muaj peev xwm zoo hauv ntau yam xws li cov khoom siv photonic, lub zog cia, thiab kev siv biomedical.

Tsis tas li ntawd, BN tau pom tias muaj cov khoom tshwj xeeb photoluminescence nyob rau hauv qee yam kev mob, ua rau nws yog ib qho khoom zoo rau cov khoom siv luminescent. Qhov kev tshawb pom no ua rau txoj hauv kev rau kev tsim cov khoom siv hluav taws xob zoo tshaj plaws, xws li LEDs thiab lasers, nrog kev txhim kho kev ua tau zoo thiab ruaj khov.

Tsis tas li ntawd, BN kuj tau tshawb nrhiav rau cov ntawv thov kho qhov muag, vim nws muaj peev xwm txheeb xyuas tau ntau yam ntawm cov molecules thiab cov tshuaj ntsuam xyuas nrog qhov siab thiab kev xaiv.

Zuag qhia tag nrho, tsis ntev los no kev tawg thiab kev txhim kho hauv kev siv BN rau kev siv kho qhov muag tau pom cov lus cog tseg zoo hauv kev nce qib ntawm optoelectronics thiab photonics. Nrog kev tshawb fawb txuas ntxiv thiab kev tsim kho tshiab, BN yuav zoo li ua lub luag haujlwm tseem ceeb hauv ntau yam kev siv kho qhov muag yav tom ntej.
