The hybrid nanocrystals exhibit a significant thermal stability and efficient photoluminescence peak at 500 nm, which were attributed to metal―ligand charge transfer at the interface between the oxygen atoms of 8Hq and the calcium ions of HAp, and the interfacial photofunctions were inechanochemically controlled. The interfacial bonding structures were also supported by a DV-Xa molecular orbital calculation.
