Claim Text:
1. A method of generating radiation, comprising directing energy as a pumping source at a semiconductor nanowire, nanobelt or nanosheet, the semiconductor nanowire, nanobelt or nanosheet being formed from a II-VI semiconductor material system, a III-V semiconductor material system, or a IV-VI semiconductor material system, a composition of the semiconductor nanowire, nanobelt or nanosheet varying along a dimension thereof, the energy being directed at a first position of the semiconductor nanowire, nanobelt or nanosheet, the energy being adapted to pump the semiconductor material of the nanowire, nanobelt or nanosheet at the first position thereof, wherein the method further comprises substantially simultaneously directing energy as pumping source at the semiconductor nanowire, nanobelt or nanosheet at a second position thereof, the energy being adapted to pump the semiconductor material of the nanowire, nanobelt or nanosheet at the first position thereof, the second position being different than the first position, the semiconductor material of the nanowire, nanobelt or nanosheet at the second position being different than the semiconductor material of the nanowire, nanobelt or nanosheet at the first position .
