Wang DeYin los ntawm Lanzhou University @ Wang Yuhua LPrge lub teeb hloov liab Nyob rau tib lub sijhawm raws li Redshift ntawm CE3 + Emission, no hloov chaw, no hloov chaw, tseem ceeb tshaj plaws ntawm CE3 + thiab txo nws qhov ruaj khov.
Lanzhou University Wang Deyin & Wang Yuhua Lpr Hloov Balu2al4.6) O12 +, nrog QEOX: CE3 +, nrog QEOX: CE3) Nyob rau tib lub sijhawm raws li Redshift ntawm CE3 + Emission, no hloov chaw, no hloov chaw, tseem ceeb tshaj plaws ntawm CE3 + thiab txo nws qhov ruaj khov. Qhov kev hloov pauv hloov tau vim yog hloov chaw ntawm MG2 + - SI4 + uas ua rau hloov chaw hauv cheeb tsam crystal frystal thiab post scormetry ntawm CE3 +.
Txhawm rau ntsuas qhov ua tau zoo ntawm kev siv tshiab tsim daj learcors rau high-zog laser laser illuminations, lawv tau tsim ua cov log phosphor. Nyob rau hauv lub irradiation ntawm ib lub xiav laser nrog lub zog hluav taws xob ntawm 90.7 W mM - 2, luminous fluinescent hmoov yog 3894 lm, thiab tsis muaj qhov pom tseeb emission prenomenon. Siv cov xiav laser diodes (LDS) nrog lub zog hluav taws xob ntau ntawm 2518.1 l
Cov txiaj ntsig tau qhia tias cov khoom siv daj tshiab zoo nkauj muaj peev xwm muaj peev xwm muaj peev xwm hauv High-zog Laser Freat illumination daim ntawv thov.
