The authors report clear evidence of radiative and nonradiative energy transfer from CdSe quantum dots to Nd3+ ions in a glass system synthesized by melting method. An efficient control can be obtained controlling the mean radius dots. Increase about 100% near infrared emission (4F3/2 → 4I9/2) was observed as function thermal annealing time.
