Band Gap Tuning and Room-Temperature Photoluminescence of a Physically Self-Assembled Cu2O Nanocolumn Array

“…Various inorganic semiconductors have been explored with much attention due to their ease of fabrication with high chemical and thermal stability and tunable electronic properties in the numerous prospective fields of applications like field emission,catalysis,gas sensor, − optoelectronics, , and solar cells with a band gap of 2.17 eV that enables it to be a promising material for the conversion of solar energy into electrical or chemical energy, (ii) it effectively adsorbs oxygen molecules that scavenge the photogenerated electrons to restrict the recombination of excitons, which plays a very important role in the improvement of the efficiency in photocatalytic processes, and of course (iii) it is low toxic and earth abundant. Syntheses of one-dimensional nanostructures of Cu 2 O − using techniques like electrodeposition, , thermal annealing, stress-induced method, etc.…”

“…3 Cu 2 O is an important material as catalyst due to its high stability, low toxicity, low cost and availability. It has importance in gas sensing, 4 CO oxidation, 5 photocatalysis, [6][7][8][9] photocurrent generation, 10 organic synthesis, [11][12][13] photochemical evolution of H 2 , 14 solar cells 15 and electrochemical 16 applications. There are some reports for producing H 2 and O 2 by nano-size metal and alloys.…”

Impact of the Plasmonic Metal Oxide-Induced Photocatalytic Processes on the Interaction of Quantum Dots with Metallic Nanoparticles

“…48 Therefore, the annihilation of the QD emission in the absence of NISs, as shown in Figures 5e and 6b (line 6), can be attributed to their strong photo-oxidation by such oxide nanoparticles (Figure 7b). 49,50 This process significantly modifies the DEs of the QDs, offering more defect trap sites for the photoexcited electrons in their cores. This leads to ultrafast nonradiative decay processes that can overwhelm the radiative decay of the QDs and annihilate their emission.…”
