Wang deyin kusuka eLanzhou University @ wang yuhua LPR uthatha indawo evulini le-balu2al4sio12 nge-MG2 + - I-SI4 + Pilal a New Blue Blue Fluet Fluorescent Powt Balu2 (MG0.6 + I-CE3 +, esebenza ngokusebenza kwe-Quantum (Eqe) ye 66.2%. Ngasikhathi sinye njenge-redshift of CE3 + Emission, lokhu kufakazelwa nakho kunwebe ukukhishwa kwe-CE3 + futhi kunciphisa ukuzinza kwayo okushisayo.
ILanzhou University Wang Deyin & Wang Yuhua LPR ithatha indawo ye-Balu2Al4sio12 nge-MG2 + - I-Blue Blue Fluet Fluorescent Balu2 (MG0.6all: CE3 + ilungiselelwe isebenzisa i-AL3 + - I-AL3 + + i-Quantum esebenza kahle (Eqe) ye 66.2%. Ngasikhathi sinye njenge-redshift of CE3 + Emission, lokhu kufakazelwa nakho kunwebe ukukhishwa kwe-CE3 + futhi kunciphisa ukuzinza kwayo okushisayo. Izinguquko ezibukekweni zibangelwa ukufaka esikhundleni se-MG2 + - Si4 +, ezibangela ushintsho ensimini ye-Crystal yasendaweni kanye nokulinganisa okuzenzakalelayo kweCE3 +.
Ukuhlola ukuthi kungenzeka yini ukuthi kusetshenziswe ama-phosphors asanda kuthuthukiswa ama-Lyinenescent ukuze akhanyiselwe ama-laser aphezulu we-laser, akhiwa njengamasondo e-phosphor. Ngaphansi kwe-irradiation ye-laser eluhlaza okwesibhakabhaka enobunzima bamandla ka-90.7 w mm - 2, umkhuhlane okhanyayo we-fluorescel powder ngu-3894 LM, futhi akukho okusobala kokuphuma kwe-Emission Fenomenon. Kusetshenziswa ama-Blue Laser Diodes (LDS) anobunzima bamandla ka-25.2 W mm - 2 ukujabulisa amasondo aphuzi we-phosphor, ukushiswa kombala okukhanyayo kwe-5983 K, ukuxhumanisa kombala okungu-65.0, kanye nombala we (0.3203, 0.3631).
Le miphumela ikhombisa ukuthi ama-phosphors asanda kuhlanganiswa aphuzi ama-lowelses anamandla anamandla aphezulu ezihlelweni zokukhanyisa zamandla we-Laser aqhutshwa phezulu.
