英文摘要	Nowadays, the excellent performance of metal halide perovskite quantum dots (PQDs) has been demonstrated, but the stability is still a perplexing issue. In this paper, the CsPbBr3 QDs were assembled into SBA-15 for the first time. The thermal stability and photoluminescence (PL) intensity of SBA-15@CsPbBr3 QDs were improved. The PL spectra of pure CsPbBr3 QDs have red-shift (similar to 6 nm) with the increasing temperature. However, that of SBA-15@CsPbBr3 QDs have almost no red-shift. The PL intensity of SBA-15@CsPbBr(3 )QDs decreased slightly after heating and cooling for several times. By comparison, the PL intensity of pure CsPbBr3 QDs decreased more significantly. The experimental results showed that SBA-15 played a significant role in improving the thermal stability of PQDs, which will have an excellent potential for the application of PQDs in the future.
