Prof. Zhijia Hu ntawm Anhui University Lub Tsev Kawm Ntawv ntawm Physics thiab Optoelectronic Engineering, Lub Chaw Haujlwm Tseem Ceeb ntawm Optoelectronic Information Acquisition and Control of Ministry of Education, thiab Anhui Provincial Laboratory of Information Materials thiab Intelligent Sensing, tau ua ntau yam kev nce qib hauv kev ua kua. siv lead ua lasers, thiab tau luam tawm plaub daim ntawv nyob rau hauv prestigious optics journals, tag nrho cov uas yog thawj chav tsev ntawm Anhui University. Nyob rau hauv cov nqe lus ntawm hluav taws xob kev hloov kho ntawm cov kua siv lead ua bandgap laser, pab neeg paub 160 nm ({1}} nm) bandgap laser wavelength modulation los ntawm kev tsav cov kua siv lead ua bandgap txav los ntawm DC voltage. Cov fluorescence spectrum ({2}} nm) ntawm laser dye PM597 tau siv txog li 80%. Ib tug ntau yam linear regression qauv yog siv los elucidate intrinsic kev sib raug zoo ntawm lub laser siv emitted los ntawm lub laser thiab qhov ceev ntawm photonic xeev, fluorescence quantum yield thiab sab hauv scattering, uas muab theoretical kev them nyiaj yug rau kev tsim cov kua siv lead ua lasers. Cov txiaj ntsig kev tshawb fawb tau luam tawm nyob rau hauv cov ntaub ntawv pov thawj "Efficient Fluorescence Utilization thiab Photon Density of States-Driven Design of Liquid Crystal Lasers". "Cov txiaj ntsig kev tshawb fawb tau luam tawm hauv phau ntawv pov thawj ntawm optics, Laser & Photonics Reviews (DOI: 10.1002/lpor.202301122; thawj tus kws sau ntawv yog Guangyin Qu, tus kws kho mob cov tub ntxhais kawm). Los ntawm kev hloov qhov kub-tsav ua haujlwm ntawm cov kua siv lead ua kua bandgap, lub laser wavelength txuas ntxiv hloov ntawm 560 nm (daj) mus rau 700 nm (liab), thiab Kev siv lub zog laser yog txhim kho los ntawm ntau tshaj 200 zaug los ntawm kev siv lub hauv paus ntawm qhov chaw plasmon resonance nyhuv ntawm kub nanorods. Cov kev tshawb fawb tau luam tawm raws li "Ntau thiab tunable kua siv lead ua random laser raws li plasmonic-enhanced FRET" hauv APL Photonics (DOI: 10.1063/ 5.0134978; thawj tus sau yog Dr. Qu Guangyin).
Daim duab 1: Schematic daim duab ntawm cov kua siv lead ua laser, simulation ntawm cov kua siv lead ua photon ceev, thiab laser spectra nyob rau hauv txawv hluav taws xob teb.
Daim duab 2. Schematic daim duab ntawm lub laser thiab kis tau tus mob spectra ntawm lub laser ntaus ntawv ntawm txawv kub.
