Ho 3 + /Tm 3 + /Yb 3 + tri-doped glass ceramics with white light emitting have been developed and demonstrated. Pumped by 980 nm laser diode (LD), intensive red, green and blue up-conversions (UC) were obtained. The green emission is assigned to Ho 3 + ion and the blue emission is assigned to Tm 3 +
