Confocal image of the sample. (a) Filtering with the atomic vapor cell (T = 200°C). The pixel size is 100 nm. The integration time per pixel is 10 ms. (b) Same area as before by using the commercial filter. (c) Line-cut of single molecules emission extracted from the above image (yellow dashed line).
