Abstract  This paper reports the observation of the ultraviolet up-conversion lumines-cence phenomenon of noncrystalline ErP5O14 excited by pulse 532nm laser. The up-conversion mechanism is explained as follows, namely, when noncrystalline ErP5O14 is excited by 532nm laser, the excited population is mainly deposited in 4S3/2 level because of the strong nonradiative relaxation between 2H11/2 and 4S3/2 level, then up-converted to (2H2G)9/2 level by energy transfer between Er3+ ions, this produces the ultraviolet luminescence.
