Numerous structures have been reported in search of affordable self-powered broadband photodetectors, however with limited success. The hybrid perovskite heterostructures have been attracted great attention due to their advance optical and electrical properties. The stability and facile synthesis are critical ...
the absorption spectrum48. In that specific case, the PL intensity was significantly reduced for higher excitation energies (>4.6 eV/<270 nm), which was explained by the loss of excess energy through non-radiative recombination. This is clearly not the case in this study: above 4.96 ...
