We present optical study of MAPbBr3 single crystals grown from solution byinverse temperature crystallization method. Photoluminescence temperaturedependence of narrow and isolated exciton resonance showed encouragingly lowinhomogeneous broadening {\Gamma} ~ 0.5 meV, which is comparable to those ofMBE-grown III-V heterostructures, indicating high quality of the solution-grownperovskite. Excitonic origin of the resonance was proved by its superlinearpump intensity dependence in contrast to the linear behavior of thedefect-assisted recombination bands. In addition, for the first time phononreplicas were resolved in MAPbBr3 photoluminescence spectra and attributed tothe known lattice vibrational modes by comparison with Raman scatteringspectra.
