I will discuss how different types of excited states, i.e. excitons and trions can be engineered in semiconductor moiré superlattices. I will discuss two recent developments. One is the discovery of a charge-transfer trion resonance in twisted homobilayers. Another is to confine excitons in a semiconductor functional layer with twisted-hBN substrates.
