Light emitting devices comprise excitation sources arranged to excite quantum dots which fluoresce to emit light. In an embodiment, a device is manufactured by a process which involves applying an acoustic field is applied to a fluid containing quantum dots, to cause the quantum dots to accumulate at locations which are adjacent to excitation sources, and then initiating a phase transition of the fluid to trap the quantum dots in the locations adjacent to the excitation sources. The quantum dots are illuminated during the process and the resulting fluorescence is optically monitored to provide indicators of quantum dot distribution in the fluid. These indicators are used as feedback for controlling aspects of the process, such as initiating the phase transition.
