emission efficiency meaning in Chinese

发射效率
放射效率

Investigations are made of porous sic ( psc ) , both as a potentially attractive material for fabricating uv light emitting diodes ( leds ) , efficient photodetectors and hydrocarbon gas sensors , and as a novel substrate for epitaxy , chiefly because of its much higher photoluminescence ( pl ) emission efficiency than that from bulk sic
作为一种有潜在吸引力的材料，多孔sic ( psc )可以用来制备紫外发光二极管、灵敏光探测器、碳氢气体探测器和新颖的外延材料，目前被广泛研究。引起大家感兴趣的一个原因就是psc比晶体sic有更高的发光强度。
Porous semiconductor materials have been widely researched in recent years , the reason is that they have shorter photoluminescence wave length and higher emission efficiency than the origin materials , porous sic is one of them which has much higher photoluminescence ( pl ) emission efficiency than bulk sic
多孔半导体材料在最近几年引起了人们的广泛研究，其原因是由于它具有比原始材料更短的光致发光波长和更高的发光效率。其中多孔碳化硅就比晶体sic有更高的发光效率。
