The time evolution of the photoluminescence (PL) of 1300-nm emitting InGaAsN/ GaAs/GaAsP strain-compensated single quantum well (QW) in the temperature range of T 1/4 10 K - 300 K is investigated. The PL spectra observed at the early stages of copyright recombination is dominated by two transitions. These two transitions are identified as the first quantized electron state to heavy-ho... https://www.parisnaturalfoodes.shop/product-category/colour-bath-indigo/
