Nd 3+ ‐ion‐doped ZnCl 2 ‐based glasses were prepared via the melt‐quenching method. The Nd 3+ ‐ion upconversion excitation mechanism and the ability to disperse Nd 3+ ions into ZnCl 2 ‐based glasses were investigated using absorption and upconversion fluorescence spectra of Nd 3+ ions. The ZnCl 2 ‐based glass that had an average cationic radius equal to the ionic radius of Nd 3+ (98 pm) had the greatest ability to disperse Nd 3+ ions. The 20KCl·25BaCl 2 ·55ZnCl 2 glass, which had the average cationic radius nearest to 98 pm, dispersed Nd 3+ ions the most, and it had the strongest upconversion fluorescence.
