Phthalocyanine compound and its application is one of the most active research directions in the optoelectronic materials field due to their excellent optical and electrical response properties. In this review, a summary is offered that the resarch progresses of phthalocyanine compounds in different optoelectronic material application fields, and the relationship between performance and molecular structure, crystalline form of phthalocyanines used as photovoltaic materials, thin film semiconductor materials, liquid crystal materials, photoconductive materials and electroluminescent materials in recent years. It is also discussed that there are problems in application research currently. Finally, some focuses for future study are projected.
Betavoltaic batteries, as a kind of ultimate battery, have attracted much attention. ZnO is a promising wide-bandgap semiconductor material that has great potential in solar cells, photodetectors, and photocatalysis. In this study, rare-earth (Ce, Sm, and Y)-doped ZnO nanofibers were synthesized using advanced electrospinning technology. The structure and properties of the synthesized materials were tested and analyzed. As betavoltaic battery energy conversion materials, the results show that rare-earth doping increases the UV absorbance and the specific surface area and slightly reduces the band gap. In terms of electrical performance, a deep UV (254 nm) and X-ray source (10 keV) were used to simulate a radioisotope β-source to evaluate the basic electrical properties. Among them, the output current density of Y-doped ZnO nanofibers can reach 87 nA•cm −2 , which is 78% higher than that of traditional ZnO nanofibers, by deep UV. Besides, the photocurrent response of Y-doped ZnO nanofibers is superior to that of Ce-doped and Sm-doped ZnO nanofibers by soft X-ray. This study provides a basis for rare-earthdoped ZnO nanofibers as energy conversion devices used in betavoltaic isotope batteries.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
