This work demonstrates tunable and purified luminescence via one-step delamination of HPTS/OS-LRH composites (HPTS is trisodium 8-hydroxy-pyrene-1,3,6-trisulphonate, OS is sodium salt of 1-octane sulfonic acid, LRH is layered rare-earth hydroxide, R = Tb, Y) along with energy transfer. The HPTSxOS1-x-,LTbyY1-YH composites presented varied luminescence behavior depending on their physical state. In solid state, dual-color luminescence was observed: blue-dominant emissions (437 nm) for HPTS.051,-LTbH, and blue-(437 nm) to green-dominant (516 nm) luminescence for HPTS0.02OS0.98-LTbyY(1-y)H. In delaminated state in famamide, purified luminescence was present: pure blue emission (440 nm) for HPTSxOS iota-x-LTbH and HPTS0.02OS0.98-LTbyY1-yH (y >= 0.5), while pure bluish-green emission (498 nm) for HIPTS0.02OS0.98-LTbyY1-yH (y <= 0.3). Both the delamination of the composites and energy transfer from layer Tb3+ to HPTS contributed to the blue luminescence. The intriguing energy transfer process between photoactive inorganic hosts and organic guests can be utilized to fabricate hybrid materials with superior luminescence property. (C) 2017 Elsevier Inc.
