Hardness is an important property of glasses, which depends strongly on the method of measurement. Herein, we estimate the hardness of three oxide glasses, namely, pure silica (0B), borosilicate (37B), and sodium borate (75B) glass samples at micro a

Herein, the tunable upconversion (UC) emission from KCaBO 3 phosphors, codoped with fixed Er 3+ ,Yb 3+ and various Ho 3+ -concentrations, has been demonstrated. Under 980 nm laser excitation, strong tunability from green to red color emission was suc
