Figure 2

Characteristic experimentally-recorded emission spectra of: (a) the SiV-luminescence with 561-excitation, (b) Fluo-4 NW without the DHT with 473-excitation and (c) Fluo-4 NW following the DHT-heating protocol utilizing both 473 and 561 nm excitation lines simultaneously. The fluorescence signal is filtered out using a combination of short pass and long pass filters in the 505–550 nm range.
