Photoluminescence study PL of the self-assembling Stranski Krastanov growth of InP nanoscale islands embedded in In0.49Ga0.51P matrix by low pressure metal organic vapor phase epitaxy are presented. The temperature and the excitation level dependencies of the external quantum efficiency of these structures were invesflgated. InP nanoislands demonstrate a high quantum efficiency at 77 K and high PL wavelength temperature stability.
