Highly efficient photoluminescence (PL) was observed from a new class of AlP/GaP quantum-confined geometry, neighboring confinement structure (NCS). The PL intensity of AlP/GaP NCSs was even higher than that of a 300-period AlP/GaP superlattice (SL), and the PL of the NCS exhibited much improved immunity against thermal quenching compared to SLs. The luminescence origin of the NCS was confirmed from the well width dependence of the PL peak shift. The peak shifts were compared with the calculation within the effective mass approximation using the previously reported band parameters for AlP and GaP.
