The temperature dependence of the energy gap of Mg x Zn y Cd 1− x − y Se ( x ∼ 0.5) and Zn 0.5 Cd 0.5 Se alloys was determined from reflectivity measurements at temperatures between 4.2 and 300 K. The data were fitted to a Bose–Einstein type relationship and temperature dependence of band gaps was compared. A similar temperature dependence of band gap was observed indicating that quantum confinement in the Mg x Zn y Cd 1− x − y Se/Zn 0.5 Cd 0.5 Se quantum wells did not depend on temperature.
