Wang Deyin wo muri kaminuza ya Lanzhou @ Wang Yuhua LPR asimbuye BaLu2Al4SiO12 na Mg2 + - Si4 + joro Umucyo mushya w'ubururu wishimye umuhondo usohora ifu ya fluorescent BaLu2 (Mg0.6Al2.8Si1.6) O12: Ce3 + yateguwe ukoresheje Al3 + - Al3 + ebyiri muri Ce3 + , hamwe na kwant yo hanze ikora neza (EQE) ya 66.2%. Mugihe kimwe no guhindura imyuka ya Ce3 +, iyi nsimburangingo nayo yagura imyuka ya Ce3 + kandi igabanya ubushyuhe bwayo.
Kaminuza ya Lanzhou Wang Deyin & Wang Yuhua LPR isimbuye BaLu2Al4SiO12 na Mg2 + - Si4 + ebyiri: Itara rishya ry'ubururu ryishimye ry'umuhondo risohora ifu ya fluorescent BaLu2 (Mg0.6Al2.8Si1.6) O12: Ce3 + yateguwe ukoresheje Al3 + - Al3 + ebyiri muri Ce3 + , hamwe na kwant yo hanze ikora neza (EQE) ya 66.2%. Mugihe kimwe no guhindura imyuka ya Ce3 +, iyi nsimburangingo nayo yagura imyuka ya Ce3 + kandi igabanya ubushyuhe bwayo. Impinduka zerekanwa ziterwa no gusimbuza Mg2 + - Si4 +, bitera impinduka mumwanya wa kristu waho hamwe no guhuza imyanya ya Ce3 +.
Kugirango harebwe niba bishoboka gukoresha fosifori yumuhondo ya luminescent yatejwe imbere kugirango imurikire ingufu za laser nyinshi, zubatswe nkibiziga bya fosifore. Munsi ya irrasi ya lazeri yubururu ifite ingufu zingana na 90.7 W mm - 2, urumuri rwinshi rwa poro ya fluorescent yumuhondo ni lm 3894, kandi ntakintu kigaragara cyo guhaga imyuka. Ukoresheje diode yubururu (LDs) ifite ingufu zingana na 25.2 W mm - 2 kugirango ushimishe ibiziga bya fosifori yumuhondo, urumuri rwera rwera rukorwa hamwe nubunini bwa 1718.1 lm, ubushyuhe bwamabara bufitanye isano na 5983 K, ibara ryerekana amabara ya 65.0, n'ibara ry'amabara ya (0.3203, 0.3631).
Ibisubizo byerekana ko fosifore nshya yumuhondo ya luminescent ifite ubushobozi bukomeye mumashanyarazi menshi ya laser ikoreshwa na kumurika.
