A novel quantum light source is characterised within our work with laser scanning microscopy including; confocal scan maps, raman spectroscopy, photon counting time resolved, photon counting second order correlation, spectrally resolved, polarisation resolved, temperature resolved and excitation power dependent measurements. The data is available as a Microsoft Excel spreadsheet (.xlsx).

  • Confocal scan maps are presented as a 2D matrix, where the first column and first row represent the X and Y axis respectively.
  • Spectral measurements are presented in a two column format for photon energy (eV) and arbitrary intensity (a.u.).
  • Second order correlation measurements (g^(2)) are presented in two columns as time (ns) and normalised g^(2).
  • A histogram representing a statistical analysis of emitter energies (which represents the energy at which the spectrum for each emitter has reached half its maximum intensity on the higher energy side) is given in two columns, where the first column is the HM value (eV) for emitters with an obvious zero-phonon line (ZPL) and the second column is the HM (eV) for emitters without an obvious ZPL.
  • Raman data is given in two colums with the wavenumber (cm^-1) against arbitrary intensity (a.u.).
  • Time resolved photon counting data is also presented in two columns, where the first column is either time [s] or X/Y position [um] and the second column is photon counts (counts s^-1).
  • Power dependent data is given in 4 columns, where the first column is the excitation power (uW) and the further three columns are the intensity (counts s^-1) of the emitter, the substrate background and the corrected (emitter minus substrate background) intensity.
  • Polarisation data is presented in one sheet, in 4 coumns. The first and third column is the polarisation rotation for the excitation and collection (degree) respectively. The corresponding photon-counting intensity (a.u.) is given in column 2 and 4 for the excitation and collection respectively.
  • Temperature dependent data is presented in three columns, with the temperature (k), the zero-phonon line energy (eV) and the full width half maximum of the ZPL (meV) in column one, two and three respectively.
