To date, it is still a challenging topic to achieve a wide tunable emission from the same sample under the excitation of a single pump source. Herein, a new sort of nanophosphor NaYO2:Er3+/Yb3+ is prepared and characterized. In particular, the wide tunable range crossing red–yellow–green–white regions can be realized only by modulating the power density of the 980 nm semiconductor laser. The mechanism...
