1. A plasma lamp comprising:
a lamp body comprising:
a top portion;
a middle portion having an internal hollow space filled with an energy-donor atomic or molecular gas and an energy-acceptor chemical atomic or molecular gas or vapor; and
a bottom portion;
wherein the lamp body further comprises an array of a plurality of microcavities fabricated within the internal hollow space, wherein the internal hollow space and the array of the plurality of cavities are spaced apart from outer surfaces of the lamp body;
wherein the plasma lamp is configured to excite the energy-donor chemical gas by an ignition of a plasma within the internal hollow space;
wherein energy is transferred from the donor atomic or molecular species to the acceptor atomic or molecular species by a collision which results in light being emitted by specific states of the acceptor atom or molecule.
