Se multiple quantum wells (MQWs) were grown on GaAs (100) substrate by MOCVD. Their photoluminescence (PL) was studied at temperature between 77K-300K. We have observed five emission bands in Zn

Se MQWs under the 457.9um line of an Ar ion laser excitation at 77K for the first time. The three of these bands are attributed to different exciton emission

respectively.
