| dc.description.abstract | The internal quantum efficiency (IQE) of radiation for bulk CH3NH3PbBr3 crystals was quantified by using omnidirectional photoluminescence spectroscopy. The angle-resolved photoluminescence revealed that the emission with photon energies higher than the absorption-edge shows a Lambertian distribution and that the light extraction efficiency is determined by the escaping cone. The IQE value strongly depends on the photo-excitation density (P), and a CH3NH3PbBr3 crystal fabricated under the methylammonium-rich conditions gave the maximum IQE of 62.5% under P = 28 W/cm2. A further increase in P gave rise to the decrease in IQE due to the Auger effects. | en |
