基于微观IBM理论，提出转动诱导出玻色子量子相变的一种可能途径：一旦原子核在受到高能激发或作快速旋转时，假如外界提供的能量足以使玻色子完成拆对顺排，则核处于集体相与单粒子态的共存相，其特征是出现较密集的能谱；假如能量不足以完成拆对或顺排，可能发生两种情况之一，当核旋转达到某个临界转动频率ω c时，或者一个高角动量的玻色子脱离"集体"而"游离"出来，或者发生一个高角动量的玻色子转变为一个低角动量的玻色子，核仍旧处于集体相；均会伴随出现光辐射，产生基态带的一条能级——相变信号。

At Er~(3+) doping concentration range 0.1-1.5 mol%, Er~(3+) first arrived at ~4F_(7/2) energy level by excited state absorption, then rapidly relaxed to ~2H_(11/2) and ~4S_(3/2) energy levels, the population of which increased, the remarkable upconversion green emission was obtained when Er~(3+) directly went back to ground state by radiative transition.

Er~(3+)浓度在0.1-1.5 mol％时，Er~(3+)通过激发态吸收跃迁到~4F_(7／2)能级，后迅速无辐射弛豫到~2H_(11／2)、~4S_(3／2)能级，~2H_(11／2)和~4S_(3／2)能级上Er~(3+)的布居数增多，Er~(3+)直接辐射跃迁回基态，上转换发射以绿光为主。
