Advanced Optical Materials, EarlyView.Theoretical lessons are key for molecules presenting an inverted singlet‐triplet excited state (e.g. S1 and T1) energy difference. This perspective provides a snapshot of the role played by calculations in last years, not only to anticipate experimental findings but also for driving high‐throughput virtual screenings, as well as the main challenge to ...

Observation of Laser Cooling on an Electric‐Dipole‐Allowed Transition in Cr3+:LiSAF Crystal
Advanced Optical Materials, EarlyView.In this work, an electric dipole allowed transition in Cr3+:LiSAF crystals is investigated for the purpose of optical refrigeration. A cooling efficiency approaching 10% is experimentally determined using a mode‐mismatched dual‐beam thermal lens method with 1 µm excitation in an unoriented 1% Cr3+:LiSAF sample.

Polymer Dots Exhibiting Multi‐Resonant Thermally Activated Delayed Fluorescence for Cellular Imaging
Advanced Optical Materials, EarlyView.By copolymerizing with a host material, a multiple resonance thermally activated delayed fluorescent (MR‐TADF) emitter quinolino[3,2,1‐de]acridine‐5,9‐dione (QAO) is successfully assembled into water‐dispersible polymer dots (Pdots). Photophysical measurements and multichannel fluorescence imaging studies show that the narrowband emission from the MR ...
