| Abstract: | We report strong visible photoluminescence (PL) at room temperature from BN nanoparticles encapsulated in ZSM-5. The investigation of powder X-ray diffraction, X-ray photoelectron spectroscopy, adsorption of N2, UV–Vis absorption, and PL spectra shows that BN nanoparticles have been successfully encapsulated in ZSM-5. Intense blue PL can be obtained from the BN/ZSM-5 sample. Analysis of PL spectra leads us to propose that the luminescence may originate from the bound excitons at the defects or impurities in the BN nanoparticles, a quasi-direct-gap semiconductor material transferred from indirect-gap BN by encapsulation in ZSM-5. |
