• A series of organic-inorganic hybrid materials BN-T1Ex (T = Tb(BA)3, E = Eu(BA)3) have been synthesized through controllable encapsulation of Tb and Eu complexes into a porous BN host. Under ultraviolet (UV) light excitation, the as-prepared BN-T1Ex samples show characteristic emission peaks of both Tb3+ and Eu3+ ions. The photoluminescence (PL) excitation and emission spectra and fluorescence lifetimes have been measured and discussed in detail. The results reveal that in the BN host, efficient energy transfer from Tb3+ to Eu3+ ions has occurred. By adjusting the ratios of Tb and Eu complexes, the hybrids realize tunable multicolor from green to red. In addition, the emission color of the hybrids can be further changed by adjusting the excitation wavelength and/or introducing of ancillary ligand phen (1,10-phenanthroline) into the samples. The obtained color-tunable organic-inorganic hybrid materials may have potential application in display devices and the UV white-light-emitting diodes (w-LEDs). This work developed BN-based hybrid materials with tunable multicolor emission by loading of Tb/Eu complexes into porous BN hosts. [Display omitted] •Tb/Eu complexes are loaded into porous BN to obtain hybrid luminescent materials.•There is energy transfer from Tb3+ to Eu3+ in the hybrid system.•The emission color of the hybrids can be finely tuned.•The hybrid materials may have potential application in display devices.
