Abstract Photoconductive properties of a polymer designed to be photorefractive are investigated. The polymer is composed of photoconducting PVK [poly(n-vinylcarbazole)], photosensitizing TNF (2, 4, 7-trinitro-9-fluorenone), and optically nonlinear DANS (4-N, N-dimethyl-4′-nitrostilbene). The electric-field dependence and $\lambda$ dependence of its photoconductivity and photocarrier generation efficiency have been measured. And preliminary four-wave mixing experiments have been carried out.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
