  Diluted magnetic semiconductor (DMS) nanostructures are promising platform to
modulate carriers and spins for new information devices. Here we report that
the high quality pure CH3NH3PbBr3 nanorods and Mn doped CH3NH3PbBr3 nanorods
have been prepared by solution method and in which the exciton magnetic
polarons (EMP) formed in Mn doped NRs, and a single mode lasing phenomenon from
collective EMP in single NR have been detected when excited by fs pulse laser.
This finding helps to understand the exciton and spin interactions and pave
ways to the realization of new type of bosonic laser.
