摘要	Photoluminescence (PL) spectra of ZnTe/Zn1-xCdxTe (x = 0.23) strained-layer superlattice (SLS) samples were studied at hydrostatic pressures up to 4.8 GPa at room temperature. A sublinear pressure dependence of the PL peaks for both the heavy-hole exciton and the donor-acceptor pair was observed. The first- and second-order pressure coefficients of the PL peaks were obtained by a least-squares fit. An analytical expression for the heavy-hole exciton was also derived. The pressure coefficients obtained from the analytical expression are 104 meV GPa(-1) and -4.44 meV GPa(-1), in excellent agreement with the experimental values of 103.9 meV GPa(-1) and -4.5 meV GPa(-2). It is shown that the contribution to the linear pressure coefficient comes exclusively from the hydrostatic component. Both hydrostatic and biaxial terms are responsible for the second-order pressure coefficient, with a negative contribution of -6.07 meV GPa(-2) and a positive contribution of 1.63 meV GPa(-2), respectively.
