最近,我们发现非氢化的无定形碳(a-C)在室温、真空并由5种LD激光诱导,当功率密度在1 kW/cm2到1 MW/cm2之间时,出现上转换连同下转换级联的量子过程,并呈现可见、刺眼的强白光辐射.在10种纳米材料中发现了类似的现象,但a-C的能量转换效率最高,超过50%,隐含着潜力.它可能是纳米的特征辐射,也是一个激光的逆过程.
최근,아문발현비경화적무정형탄(a-C)재실온、진공병유5충LD격광유도,당공솔밀도재1 kW/cm2도1 MW/cm2지간시,출현상전환련동하전환급련적양자과정,병정현가견、자안적강백광복사.재10충납미재료중발현료유사적현상,단a-C적능량전환효솔최고,초과50%,은함착잠력.타가능시납미적특정복사,야시일개격광적역과정.
Recently, we have found visible, white and dazzling strong radiation induced by lasers(5 kindsof LDs) from non-hydrogenated amorphous carbon(a-C) at room temperature in vacuum with upcon- version and downconversion cascaded quantum process under the laser power density between 1 kW/cm2 and 1 MW/cm2. This phenomenon also exits for other nanostructured materials(10 types) but the energy transformed efficiency of a-C is much higher, more than 50 %, which implies potentials. It may be characterized as nano-radiation and it is also a reversed lasing process.
