Abstract
Disclosed herein are modified chromium-dpoed zinc gallate (ZGC) nanocubes, which are characterized in respectively having a concave surface that is modified with (3-aminopropyl)triethoxysilane (APTES). The modified ZGC nanocubes produce long lasting luminescence (LLL) that lasts for at least 1.5 hours under X-ray or UV excitation. Also disclosed herein are methods for the preparation of the modified ZGC nanocubes; and methods for imaging an area of interest (e.g., cancer) in a live subject using the modified ZGC nanocubes as an imaging agent.
