摘要：
The spontaneous emission quantum efficiency of molecular beam epitaxy grown InGaAs/GaAs quantum wells is determined using photoluminescence measurements. The quantum efficiency is inferred from the power law that links pump power and integrated photoluminescence signal. (C) 2008 Optical Society of America
