%X The obtention of spontaneous Raman photons is analyzed in singly charged p-doped quantum dots in the absence of an external magnetic field. The use of a far detuned single driving laser allows to obtain a Raman photon line which exhibits subnatural linewidth, and whose center can be tuned by changing the detuning and/or the Rabi frequency of the driving field. The Raman photons are produced along the undriven transition and they arise from the weak interaction of the trion states with the nuclear spins. The operating point for the gate voltage of the heterostructure can also be used to modify the linewidth and the peak value of the fluorescent signal.
