Efficient ultra-broadband emitter is realized by using multi-Ln-doped Cs2Ag(In/Bi)Cl6 lead-free double perovskite (DP) coupled with “DPs-in-glass composite” (DiG) structure. The synergy of self-trapped exciton together with the energy transition induces this ultra-broadband emission emerge.
Using meta-imagers, all-optical convolutional processing that arbitrarily reshapes the point spread function of an optical system can now be implemented.
A recent publication shows that chip-nanoscopy is a suitable technique for histopathological assessment. This development opens the door to the clinical implementation of optical nanoscopy in tissue damage assessment.
