The temperature dependence of the energy gap of zinc‐blende CdSe and Cd 1-x Zn x Se has been determined over the entire range of composition from optical transmission and reflection measurements at temperatures between 5 and 300 K. The experimental results can be expressed by the following modified empirical Varshni formula, whose parameters are fu...

... When comparing temperature dependence of maximum emission energy for NBP:CdSe/ZnS(0.3) and NBP:CdTe composites with bandgap energy of bulk CdSe [19] and CdTe [20] (Figure 5), it can be noticed that in the case of both QD-doped materials it changes with increasing temperature faster than bandgap energy of a bulk semiconductor. It indicates that the emission originates from a quantum structure rather than from a solid material, that would be created if the QDs had melted into the glass matrix. ...
