The growth process, stability of GaP nanocrystals and the formation of Ga 3 P nanocrystals under solvothermal conditions were investigated. At moderate reaction times and temperature, the growth process is mainly in accordance with the Ostwald ripening mechanism, which is the dissolving of the smaller GaP crystallites and growth into larger ones. However, GaP nanocrystallites become unstable under increasing reaction temperatures or prolonged reaction times. EDAX and XRD were used to identify the new Ga 3 P phase.
