Direction- and polarization-tunable spontaneous emission beneficial from diffraction orders of a square R6G-nanopore array.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
To meet the miniaturization and compatibility of current micro-nano optical devices, two-dimensional (2D) photonic crystals (PCs), which can manipulate the optical parameters and their propagation with more degree of freedom, have become more important in nano optics. In the case of 2D PCs, the specific symmetry of the microscopic lattice arrangement determines its macroscopic optical properties. In addition, beyond this key element of lattice arrangement, the unit cell of PCs is also a critical factor in modulating the far-field optical behaviors. This work explores the manipulation of spontaneous emission (SE) of rhodamine 6G (R6G) in a square lattice of anodic aluminum oxide (AAO) membrane. The directional and polarized emissions are observed to be related to the diffraction orders (DOs) of the lattice arrangement. By further tuning the size of unit cells, different DOs are triggered to overlap with the emission of R6G, resulting in an extended tuning for directions and polarizations of light emission. It exhibits the significance for the design and application of nano optics devices.
