A wavelength conversion member comprising:
- a tube;
- a host in the tube;
- an air layer in the tube;
- and
- a plurality of quantum dots in the host;
- wherein the tube comprises:
- a first distal end;
- a second distal end opposite to the first distal end;
- a first tube portion;
- a second tube portion adjacent to the first tube portion;
- and
- a midpoint between the distal end and the second distal end along a first direction that is parallel to a central longitudinal axis of the tube,
- wherein the first tube portion extends from the first distal end to the midpoint and comprises the air layer and a portion of the host,
- wherein the second tube portion extends from the midpoint to the second distal end and comprises a portion of the host,
- wherein the portion of the host of the first tube portion has a mass that is smaller than that of the portion of the host of the second tube portion, and
- wherein a portion of the first tube portion is treated such that its surface characteristics are different from those of a portion of the second tube portion.
