Most attributes of the bulk materials, especially in the solid-state, are directly dictated by a manner by which the molecules are ordered. Thus, it is expected that the possibility of controlling these structural orders would allow predominating some particular physical

A type of dual-emission probe with highly recognizable luminescence-response to pH has been designed. For the prepared core-shell polymeric hydrogel nanoparticles probe (Eu(DBM)3Phen doped polystyrene (PS)-co-poly(N-isopropylacrylamide)(PNIPAM)/FITC), the red emission of inner encapsulated europium complexes Eu(DBM)3Phen is remained in the hydrophobic
