BiOBrxI(Cl)1−x based spectral tunable photodetectors fabricated by a facile interfacial self-assembly strategy†
Abstract
A series of photodetectors based on BiOBrxI(Cl)1−x films are fabricated via a facile and rapid interfacial self-assembly method. The photodetectors show a high signal to noise ratio, and the cutoff wavelength can be tuned over a broad range from the visible to the ultraviolet region simply by changing the composition of the BiOBrxI(Cl)1−x films.
