Abstract

The use of metal halide perovskites for optoelectronic devices beyond solar cells is gaining growing attention. Perovskites with different compositions are promising as tuneable light emitters for the whole visible spectral region [1]. We report solution processed perovskite laser devices that show amplified spontaneous emission and lasing. We have fabricated surface emitting perovskite distributed feedback lasers by spin-coating CH3NH3PbI3 precursor solutions in ambient atmosphere on nanoimprinted grating substrates [2]. These lasers exhibit narrow lasing linewidths below 0.2 nm and an excellent stability of more than 5×10^7 pulses at 1 kHz repetition rate. Lasing at different wavelengths could be achieved on a single substrate by integrating different grating periods on the same substrate. While the emission wavelength of CH3NH3PbI3 is in the deep red to infrared spectral region, the lasing emission can be shifted into the visible by a gradual exchange of iodine to bromine. By adapting the grating period to the emission spectra of the mixed halide perovskite, we achieved lasing in the visible. Furthermore, we demonstrate high-quality perovskites fabricated by ink-jet printing on flexible substrates. Such films show strong amplified spontaneous emission with a clear ASE intensity threshold.
