Sustainable phosphorescent oscillators based on photochemical deoxygenation in convections Upon constant photo-excitation, the phosphorescence intensities of long-lived triplet emitters dissolved in sulfoxide solvents under air exhibit periodic oscillations with regulatable frequencies and amplitudes, which is attributed to the interplay between photochemical deoxygenation and Rayleigh-Bénard convections.

AbstractMaterials exhibiting a significant shift current response could potentially outperform conventional solar cell materials. The myriad of factors governing shift-current response, however, poses significant challenges in finding such strong shift-current materials. Here we propose a general design principle that exploits inter-orbital mixing to excite virtual multiband transitions in materials with multiple flat bands to achieve an enhanced shift current response.
