Photoactive p-Type Spinel CuGaO Nanocrystals.

Herein we report the synthesis and characterization of spinel copper gallate (CuGaO) nanocrystals (NCs) with an average size of 3.7 nm via a heat-up colloidal reaction. CuGaO NCs have a band gap of ∼2.

Highly Conductive and Visibly Transparent p-Type CuCrO Films by Ultrasonic Spray Pyrolysis.

The development of high-performing p-type transparent conducting oxides will enable immense progress in the fabrication of optoelectronic devices including invisible electronics and all-oxide power electronics. While n-type transparent electrodes have already reached widespread industrial production, the lack of p-type counterparts with comparable transparency and conductivity has created a bottleneck for the development of next-generation optoelectronic devices. In this work, we present the fabrication of delafossite copper chromium oxide p-type transparent electrodes with outstanding optical and electrical properties.

Fluorine-Doped Tin Oxide Colloidal Nanocrystals.

Fluorine-doped tin oxide (FTO) is one of the most studied and established materials for transparent electrode applications. However, the syntheses for FTO nanocrystals are currently very limited, especially for stable and well-dispersed colloids. Here, we present the synthesis and detailed characterization of FTO nanocrystals using a colloidal heat-up reaction.
