Salt Matrix

Cadmium acetate salts can greatly enhance room-temperature phosphorescence (RTP) of purine and 6-mercaptopurine. 6-Mercapto-substituent and 6-hydroxy-substituent appear quite different in their effect on the RTP of purine. The effects of cadium salt matrix and pH on the RTP of purine compounds were also investigated in detail. With cadmium acetate as a source of heavy atom perturbation, nanogram or subnanogram amounts of purines can be detected.

We present a design principle to activate highly efficient organic room temperature phosphorescent (ORTP) of carbon dots (CDs), with layered double hydroxides (LDHs) as the host matrix, that utilizes three synergistic effects,i.e.structural confinement effect, heavy atom effect, and chemical bonding.
