Data set for "Doubly-resonant enhancement of Second Harmonic Generation from a WS2 nanomesh polymorph with a modified energy landscape"
WS2 is an example of a transition metal dichalcogenide, and a highly promising 2D material for nonlinear optics. This dataset contains plots of multiphoton emission spectra and coordinates of second harmonic generation (SHG) hotspots of WS2 polymorphs and thin films formed into a nanomesh, that is, a tridimensional webbed network of densely-packed stacks (of 1–5 layers) of twisted and/or fused 2D nanosheets. The locations of the emission hotspots were determined by illumination at 1225, 1050, and 850 nm incident wavelengths.

Data collection method:
Multiphoton imaging: Samples were illuminated from 850 to 1300 nm in incrememnts of 25 nm with a constant average power of 0.5 mW. Images of the emission from 425 to 650 in 32 steps were taken.
Data processing and preparation activities:
An in house script was used to take the resulting images, convert them to greyscale and averaging the pic intensity in the area specified using the coordinates chosen or the whole of the image. The resultant data was then plotted.
Technical details and requirements:
Zen Blue was used to obtain the data and Zen Black to convert the .czi to .jif files. A python script was then used and results in a .csv file. Origin was then used to plot the data.
Additional information:
Hotspot coordinates are provided in MS Excel format. The plot of pixel intensity versus wavelength is provided as an Origin Unicode Project file, which may be inspected with the Origin Viewer application.
