摘 要：The possibility of tuning between red,green and broadband white color of up-conversion was demonstrated in thermally 450 oC treated Yb/Er co-doped nano NaYF4 phosphor.The color variability was studied by means of power dependence of luminescence,which ex-hibited unusual behavior.Large hysteresis,as well as discrepancy from a power law indicated the important role the increased heating played during the up-conversion in nano-sized materials.
