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 +

The optical properties of the rare elements Tm 3+, Ho 3+ and Yb 3+ were systematically investigated in various glasses. The Tm 3 + doped aluminozircofluoride glass shows higher quantum efficiency, longer lifetime and stronger fluorescence intensity than Tm 3 Γ· doped YSGG crystal and other Tm 3 Γ· dop
Yb 3+ -Tb 3+ and Yb 3+ -Tm 3+ -Tb 3+ doped fluoro-germanate glass samples were fabricated in bulk and fibre form. Bright up-conversion has been obtained by exciting the samples with a 975 nm laser source, and the power dependence of the up-conversion intensities with respect to the excitation power
