Fluorescein isothiocyanate and rhodamine B dye encapsulated mesoporous SiO2 for applications of blue LED excited white LED
Source abstract
Abstract
Abstract In this work, the fluorescein isothiocyanate (FITC) and rhodamine B (RhB) dyes were encapsulated in mesoporous silica nanoparticles (MSNp). The MSNp-FITC-RhB nanohybrids phosphor showed a dichromatic PL emission at green region and orange region when excited at 460 nm. A Forster Resonance Energy Transfer (FRET) was observed from FITC to RhB. The materials were further characterized by XRD, FTIR, TEM, and temperature dependent photoluminescence. The CIE coordinates were tuned from greenish yellow to the orange region and quantum yield was reached 52.04% based on FRET. So by combining the MSNp-FITC-RhB nanohybrids phosphor with the blue LED chip, the white light emission with flexible Color Correlated Temperature and improved Color Rendering Index can be obtained.
