Abstract

Hybrid semiconductors of the general formula 2D-[Cd2Se 2(ba):Te] (ba = bultylamine) emit direct white light upon illumination of UV-LED. The band gap and photoluminescence properties of this group of materials can be systematically tuned by changing the composition and doping level. The sample with 25 mol% of Te corresponds to the CIE coordinates of (0.29, 0.35), which is closest to the equi-energy white point (0.33, 0.33). These hybrid materials are also highly photoconductive with large gain under illumination of visible light.
